USO: Ultimate Special Offers

Decided to give this a shot for BF/CM, and I can only say that I'm 100% completely dissatisfied. I created a discount for the sale, and checked how it worked on my site. It seemed fine, so I went ahead and blasted my email list and Facebook. I then started getting all sorts of notifications that the discount wasn't showing up sometimes. I did a test again on my end - first time, it seemed fine... second time it had stopped showing a discount. Then, my Cart and Checkout actually stopped working altogether. Now, I've flubbed the beginning of my sale, and I have to refund several customers for the discount difference. I highly recommend you find another app for this sort of thing.
