The Google eBookstore is a great way for independent bookstores to sell eBooks, but there is still quite a range when it comes to prices. Last week when the store launched, we reported that Stieg Larsson’s popular title The Girl Who Kicked The Hornet’s Nest eBook cost anywhere from $9.99 to $27.95.

We checked it again today and found that for the popular title The Immortal Life of Henrietta Lacks by Rebecca Skloot, prices vary a lot among different Google eBook vendors.

Google sells the eBook for $9.99, down from the list price of $26.00. Bay area independent bookstore Alibris has the eBook listed at $16.90. And Politics and Prose, an independent bookstore based in Washington DC, is selling the eBook for $18.20.

The eBook is $9.99 in the Kindle store. If Google is going to match Amazon for extremely low pricing, then indie booksellers are going to have a tough time competing.
