I have not yet been able to create an interface on my store for automated BitCoin transactions, but I will accept private orders!  My prices are always highly competitive (almost always lower) than the buy it now prices you'll find on eBay.

I have about 500 games available on my store right now, and I'm adding 100-300 every weekend.  As of this post, the exchange rate is 1:1, but it will vary based on the Mt Gox exchange rate day to day.  Do not bother making offers that low ball the USD price (ie: 10 bitcoins for a $12 USD game).
