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.

This add-on launches many requests without any user interaction if it detects a coupon code section on a page. Sometimes it'll roll through as many as 20 different codes, applying each of them to determine the amount saved. Often times this automatic runaway process straight up breaks sites or shopping carts by triggering rate limiters or overriding manually-selected discounts/affinities. The settings are - I believe - somehow managed through the capitaloneshopping web site, but it is not at all clear what settings will change what behavior in the add-on. If the Capital One name were not tied to this add-on then I would instantly disregard it as malicious. The links section here all point to generic web pages that are not at all related to the add-on which frankly behaves like it's compromised.

So far, OK, but not always sure when it is working!

Seems to work good but often it does not offer ANY savings?
