LemMeBuyIt

LemMeBuyIt brings live retail product data from 100+ U.S. retailers into ChatGPT. Search a store's catalog by keyword, UPC/GTIN/EAN barcode, ASIN, brand or category and see the current price, original price and discount. Match the same item across stores by barcode to compare prices, and browse active promotions and coupon codes with their end dates.

With weekly price history, you can check whether a markdown is a real deal: the history merges the retailer's price with the matched Amazon Buy Box over up to two years. For resellers, find_flips ranks resale candidates by ROI after marketplace fees and gives each row a BUY or THIN call. check_listing_eligibility checks whether your own connected Amazon seller account can list those items.

Limitations: all tools are read-only. LemMeBuyIt doesn't place orders, add to cart or take payment; purchases are completed on the retailer's own site. Prices and promotions come from retailer data that refreshes at different rates, so each result shows when it was last updated. Flip results are estimates to verify before buying. Some features depend on your LemMeBuyIt plan. Product links may be affiliate links, and responses include a disclosure.
