SonyStyle is offering $50 discounts on two of their ebook readers for a limited time. The 5″ Sony Pocket Edition (recently reviewed on The Gadgeteer) is on sale for $149 if purchased from SonyStyle by May 9th. SonyStyle suggests the Pocket Edition would make a great Mother’s Day gift, and I agree. The $50 discount is also available for the wireless 7″ Daily Edition; it will be available for $349.99 until May 22. The Daily Edition would also make a great gift for Mom or anyone who loves to read.
