Not sure about this site. I tried once and, yes, a lower price was indicated. BUT I would have had to pay full price and get some kind of coupon to use for something I didn't care for. I'm sorry I'm so vague, but it was several years ago and my brain is tired and retired.

The absolute best coupon extension hands down

ADD-ON IS SIMPLE AND QUICK. SAVES ME MONEY!

It's not doing anything that I can see

Extension has never worked since before capital one bought it from wikibuy. Promotions DON'T WORK, Coupons DON'T WORK, and worse is that contacting Capital one about the problems with their app DOESN'T WORK either. Samuel L. Jackson is awesome but this Mother F$^%#@& Capital One Shopping app DOESN'T WORK or do anything but waste your time.
