I too suspect it was just a simple mistake, but regardless check your accounts to verify them before it is too late to make adjustments.
I called the Borders store where I made the purchase and subsequent return and told them my situation. She asked what product this was for and I told her the KT. She said that they were aware of their mistake and had been trying to get in touch with me but apparently had an incorrect phone number. So it looks like I will get this resolved this afternoon when I go to the store. I was never worried about their honesty, but I was concerned about dealing with a company in liquidation. But it appears everything will work out okay.
On another note, this store in Arlington, TX is selling the Kobo WiFis for $79 if anyone is interested. There phone answering recording said that anyway.
