I would like to enter the giveaway...
Anyway, here are some of my suggestions, even though they aren't that great.
As I first entered the site, the things that caught my eyes were the colors. Usually, red means stop, restriction, none, and green means available, go, etc. I thought that if you changed the colors, for ex. Using the color red when you run out of stock, and using like green to list the price, to show that it's available. It's not that big of a deal, but just a thought lol
Also, I think that the "Tech Support" under the "Help" tab should have a little box to type in the message, like the one built in the "Contact Us". I think that if you do this, it would be easier to separate the complaints and issues of the product from the general questions/comments, so that you could have a person who specializes in tech stuff answer tech questions, and have other members answer general questions. I think that will prevent any problems in the future...Maybe.
