Target has a sale on its M-edge stuff for Nook and Kindle. I ordered the executive case for the Nook
and they also have one of the other trip jackets
. They offer free ship on the m-edge sleeves and I figure I can return it in the store if it doesn't end up fitting and just get one off of etsy.
If you're going to bite the bullet and go with the Sony case, Howard's has it cheaper than anywhere else and has free shipping. They also let you use paypal.
