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.
