A number of folks in a Yahoo! Answers thread claim to have tried ordering from the site only to have their credit cards declined. A suspicion expressed frequently in the thread is that the site is collecting credit card information for nefarious purposes.
I bought one off of eBay for $189, arrived yesterday. The seller is "intimate4you" -- seems to be selling big batches of N800 tablets that were store demos. $207.30 shipped (w/insurance.)
