These have been sold on Shop Goodwill in the past. This one is London, ONT, Canada, so the shipping should be cheaper for Canadian bidders (about $20 if shipped to Idaho). It's an auction and there's six days left. Just thought if someone was looking for a new Kobo Mini they might want to know about this one. I have no idea how well the battery lasted during its long storage. I'm guessing the Mini won't go cheap.
