Who hates this ? It's a freaking app to help save you money! Sure, not all codes work for every purchase for everyone but, goodness!! I'm honestly shocked at the 100+ people who gave this 1 star. The problem today is too many people expecting everything to go their way. Life doesn't work like that. This world.... Anyways, if you'd like to possibly save a few bucks possibly on your favorite sites, I highly recommend this add -on. If you order Pizza, or just shop online it's a no brainer. So you may not get any discount. When has it ever hurt to try?? I've saved on shipping. I've gotten $5 off my pizza order. In today's times, when does the surprise savings of a few dollars ever hurt? Exactly! Ignore the petty whinny ass people and at least give it a shot. What can you lose besides a couple dollars off your order?? The few seconds to install or uninstall. I feel for the rest who didn't get it all for free. SMH. Just try it!
