No, discover is tricky. You can not trace your purchase with shop discover. I used to shop with it a lot, and they miss quite a lot of my purchase. It is not as reliable as chase's program or BOA add it up, nor even close to them. Now I use shopper or mrrebates for the cb, feeling much better than discover. One reason I chose discover before was it was the only card that can be used in Sam's club. Now things have changed.
