Hmmm. Thier website currently just consists of this statement:
"Dear valued customers,
All of us at Edge Micro would like to thank you for the opportunity to serve you for the past 5 years. Unfortunately, because of issues that have come to surface within the past few months, we are no longer conducting business. Again, thank you for your business.
Sincerely,
Edge Micro"
Guess they are out of business then.

These people look like slime (they have a six month rating of 0.26 (!) and a lifetime rating of 1.42). Moral of the story is threefold:
1. Never purchase computer parts on-line with anything but an actual credit card.
2. Also check the Reseller Rating of the company before you use them.
3. Just shop at Newegg and save your sanity.
Sorry, I don't think there's anything anybody can do, other than to try to get the bank to reverse the charges (or attempt to sue them, I guess).
