I picked up Antique Depots as an expiring PR3 domain. I got it setup with my newest theme tonight.
I was also doing a little work with the Amazon API to try and start testing that out like many of you suggested. I should have an Amazon niche site up by the the end of this week sometime. I got the API returning item titles, images and prices based on a keyword query. I think the Amazon API is a little more difficult to work with then eBay’s, but I think Amazons might have a lot more flexibility and features.
I have 2 more expired domains that I have to get finished setting up with WordPress and EPN before I dedicate myself 100% to the Amazon site.
