This looks great, so far.

Is it possible to change the currency symbol anywhere? Can't wait for the updated product!
I posted a test item and received a database error after submission. I noticed that if I posted, for example, the word
I've instead of
I have, I need to add a backward slash before the apostrophy like this:
I\'ve to allow the submission. This goes for all words with an apostrophy. The slash disappears when viewing the description.
I also noticed something disturbing...the seller can bid on his or her own items, so I think that should be fixed, too. I apologise if this has already been pointed out!
