I am having MAJOR problems with sales recording (has been going on since early February, actually). Amazon is apparently having pretty major issues with one (or more) of its servers. I cannot begin to tell you how frustrating this has been. However, with the high volume of sales you will definitely have from your promo, I'm pretty certain your sales will have to start appearing pretty soon. If they don't, definitely e-mail Amazon. Reading a confirmation that it's issues on their part will make you feel better (though not by much). Hold tight!
