WEM answers one question an assistant cannot answer on its own: is this actually the price you should pay? Ask for a product — by name, by barcode, or by pasting a WEM product link — and WEM returns every retailer offer it can verify for that exact item, cheapest first, with the 90-day price low so you can tell a real discount from a repackaged one. Identity is resolved by GS1 barcode rather than by matching titles, so the offers you see are the same product, not a lookalike, an accessory, or a different size. WEM compares live prices from authorised partner feeds and marketplace APIs it is licensed to use. It ranks on price and on the priorities you state — never on what any retailer pays WEM. It carries no advertisements, and affiliate commission is not an input to comparison ranking. Checkout for compared products happens on the retailer's own site, at the retailer's price — WEM never handles payment, your card or your personal details for those purchases. WEM is free to use and funded by disclosed affiliate commission, disclosed on the card itself and at wem3.ai/disclosure. What it will not do is guess. When WEM cannot verify a second price, it says so instead of inventing one.
