Evaluation

Finally, the e-commerce code I've been working on for the past few months is about ready to fly. However, since I've been so close to it (design, code, testing, etc), I might have missed something critical. Would some in this group have time to go through it with a red marking pen and give me some constructive criticism? I will attempt to keep my connection to the site up for the next 24 hours or so (ISP is having difficulty with the MySQL portion of the PHP/MySQL combo). The URL is ... http://sears.onet.net/index.php Also, for those having blazed an e-commerce site before me, could I get some input regarding good credit card processing companies regarding cost per purchase, etc? Finally, any last minute do's and don'ts regarding an e-commerce site? Thanks for your help in the past. Bob
