Compare products across open tabs and spot a fake sale
A reviewer asked Comet to compare four mattresses open in three store tabs, listing price, trial length and firmness. It did it in about 90 seconds and noticed one 'sale' price was higher than the store's own 30-day average. The same review warns that web pages can trick AI browsers, so watch it closely near payments.

Compare the products in my open tabs. Make a table with price, delivery cost, trial or return period, and [KEY DETAIL]. Tell me if any 'sale' price is higher than the item's recent price. Don't add anything to a cart.
