All five are free to use, with some usage limits. No need to learn complex commands: just describe your purchase in your own words.
For example, you need sneakers under $100. No need to study prompts: just describe the item, size and budget. AI will help you find options and links to US stores.
And next: 15 unexpected tricks ↗Find New Balance sneakers under $100 in size US 9 in US stores. Compare prices, different colorways and availability. Give direct links and mark unconfirmed data separately.
Not 15 variations of "compare prices" advice. These are different tricks: from searching by SKU to hidden discounts and calculating shipping.
Compare not only stores, but also colors of the same model. Sometimes the same silhouette in a different colorway goes on sale sooner.
Find all New Balance 9060 colorways in size US 9 in US stores. For each, give the item number, color, size availability, price in dollars and a direct link. Sort by the lowest confirmed price. Don't mix men's and women's sizes.
Check the brand's official site, specialized discount chains and outlets. Look at whether the item number is identical, the return policy and the seller's reputation.
Find the Columbia [model or item number] jacket at Columbia, Sierra, Nordstrom Rack, 6pm and other reliable US stores. Show only offers for the same model, and note size, condition, availability and price.
AI can identify the type of item and translate it into the language of US catalogs: shacket, crossbody, relaxed fit, full-zip hoodie. Then it can find similar original products.
Look at the attached photo. Identify the cut, color, material and construction details. Give 8 precise search queries in English and find similar items under $100 in US stores, no fakes.
An extra discount is sometimes applied in the cart. Look for the words extra off, applied in bag, buy more save more and check the exclusions.
For the item [link], check the store's official website. Is there a discount applied in the cart, a coupon, a multi-item promotion or a first-purchase discount? State the terms, exclusions, date and what needs to be checked manually.
Compare Rakuten and TopCashback, and consider category terms, code compatibility, country restrictions and payout method. Don't include cashback you won't receive in your savings.
For the store [name], find the official cashback terms at Rakuten and TopCashback. Check the category, promo code restrictions, and whether sign-up and payout are available for me. Don't treat cashback as guaranteed.
A crossed-out price doesn't prove a real deal. Compare the price history, the average price, and the lows over 30-90 days.
Analyze the price history from the link or the attached Keepa / CamelCamelCamel chart. Find the typical 90-day price, the lowest price, the current price, and the real difference. Don't use only the crossed-out price as a baseline.
Ask AI to find original products by material, hardware, shape, and size. Comparing by looks is only the start.
I like the Coach bag [link] for $280. Find five original alternatives under $120 with a similar shape and size, made of genuine leather. List the dimensions, material, price, and links. Don't suggest knockoffs with other brands' logos.
Compare sneakers or electronics with the previous generation by the features you actually use. Consider what's included, the warranty, the condition, and the seller.
Compare [new model] and [previous model] by the features that matter for [use case]. Find new devices at Amazon, Best Buy, Target, and Walmart. Show the price difference, the generation, what's included, and direct links. Exclude refurbished and open-box.
Compare the set with buying the same items separately. Miniatures, unneeded accessories, and "free gifts" can create an illusion of a discount.
Compare the set [link] with the price of each included item separately in the US. List the exact volumes or specs, the total price when bought separately, and the real difference. Flag miniatures and duplicates separately.
Instead of "I usually wear M," provide the measurements of your own garment and the brand's chart. This is especially important for jeans, shoes, and outerwear.
Here are my measurements: [data] and a link to the [brand] size chart. Compare the sizes of [model], suggest a range of options, explain the differences in fit, and tell me what's missing for an accurate decision. Don't promise a guaranteed fit.
Old colorways, limited editions, and past collections are often hidden from regular search. Enter the SKU and exclude unverified marketplaces.
Find the new [exact model / SKU] in US stores, including official outlets and well-known retailers. Check stock, SKU differences, condition, and the link. If the model has been discontinued, say so directly.
Deals may already be running in November. Separate the official Early Black Friday Deals from regular seasonal sales.
Find the official Early Black Friday Deals 2026 on [category] in the US that are running right now. For each offer, show the store, the check date, the deal terms, a direct link, and the price. List regular sales that aren't called Black Friday separately.
AI can compare whether it's cheaper to buy everything together or from different stores. Include US shipping costs and deal restrictions.
I have a list: [items, sizes, budget]. Compare two options: one store versus several US stores. Use real prices and free US shipping terms. Show your sources and point out any unverified costs.
A purchase is only a good deal once you factor in delivery within the US, international shipping, possible duties and other costs. Don't plug in made-up rates.
Here are my items and prices: [list]. Here are the confirmed Prostobox rates: [insert]. Compare the cost of buying from one store versus several, factor in the known costs, and list any missing data. Don't make up rates.
Price history helps you understand whether a deal is already worth it right now. But no AI can guarantee the price on Cyber Monday.
Here is the price chart and the promo terms [data]. Compare the current price with the median and the lowest price over 90 days. Assess the risk of waiting until November 30 without promising that the discount will get bigger.
Sign up with Prostobox and get a free US warehouse address so you can shop at American stores.
Pay for your order yourself using the warehouse address, or request a buyout: an operator will buy the item with a US card while it's still in stock.
We combine your parcels into one and deliver it to a pickup point of your choice. US to Russia delivery takes 5-10 days.
Choose a country and city, enter the parcel weight - we'll show the available rates and prices.
Enter the weight without packaging - at the warehouse, the box adds about 400 g. Insurance is already included in the price.
Available rates
Prices are for shipping a parcel of the selected weight. The final cost is confirmed at checkout. For items that can't be shipped, see the list.
The customs declaration that used to take you hours is now filled out by an AI assistant in one minute.
Our Support team works hand in hand with AI: as soon as you send your request, the AI checks the statuses of your parcels, whether a particular item can be bought, and other data, so by the time an operator picks up the ticket, half the work is already done. Response times have improved by 60%!
Artificial intelligence makes your orders easier and faster: instead of filling in dozens of fields, you can send a link to your iHerb cart or screenshots of product pages from any other US store!
We use AI in warehouse operations - receiving, logging and processing parcels. We've handed many routine tasks over to AI so our staff can give your purchases their full attention!
AI works on our side at every step - from the customs declaration to receiving parcels at the warehouse.
AI doesn't need a perfect prompt. You can write in plain words, attach a photo, add a budget and ask it to clarify details.
Get smart prompts ↗The button copies the prompt. Paste it into ChatGPT, Claude, Gemini, Grok or Perplexity and add the product name, a link or a photo.

Important: the source of the price is the product page on the store's website, not the AI's answer. Check the date, size, color, seller, availability, whether the coupon applies and the final total in the cart. Don't count on cashback until you've confirmed you can actually get it. Some US stores may restrict payment and shipping to forwarder addresses.
With Prostobox, you can receive purchases from US stores and consolidate parcels where the service terms allow it. First check the rates and restrictions, then ask an AI to help you compare the total cost of your options.
