Books In The iBooks Store Raised To $12.99?

Has the price of books in the iBooks store increased even before the iPad reaches your hands? In the latest leak, books that were previously priced at $9.99 now seem to be listed at $12.99 instead, which is actually in line with the prices that were glimpsed on the Apple promo material. This newly updated pricing might be in line with the licensing terms that Apple is using for the iBook store, as the company has chosen an agency model, which is generally preferred by major publishers who want more control over the price of books.
