I found this supplier from outside of our directory. It has a good inventory of Nook cases - Link hidden: Login to view

Since we haven't thoroughly evaluated this supplier I will have to say that SaleHoo does not guarantee its reliability.
I can see that they accept Paypal and credit cards, and it is advisable to use these safe payment methods, they allow you to file for a charge back if you need to. :)
Hope this helps. :)
