A friend mentioned a site where you can check before buying stuff online. I tried it last week when I was ordering a few travel items for an upcoming trip. Found a code that actually worked and saved a little on the total. Before using it, I looked at some feedback at https://chatdeal.pissedconsumer.com/review.html just to see what others were saying. The site itself was straightforward, no pop-ups or redirects. It came in handy for that one purchase.
