RSS can help you sell - but maybe in a way you didnt think of. What i did about 4 yrs ago was create a blog, its like a diary or in my case, a 'how to' site, with blog.co.uk and without realising it it became uploaded to the web and loads and loads of people worldwide now follow it online, its well worth it, and as for books, you can write a review about the books on the blog and put a link to your auctions and ebid store on it, the built in RSS feature is all included so you dont have to know what to do, i didnt have a clue! I have it pointing to my feebay store but will soon add ebid to it when i get a chance, so...go for a blog I say. Take a look at mine and you'll see what i mean, its at www.floristry.blog.co.uk/
