Suzi,
I'm glad it was resolved peacefully. ;-)
The Seller made out much better than if you had bid correctly, so I doubt they'll be complaints on that end. And you had to pay a bit for your error. Fair enough all around.
And I'll guarantee you that the other bidder knew exactly that the seller was sort of taking advantage of him/her by offering it at $69, which was unfair.
Don't stay away from bidding and eBay. This was clearly a typo error, not an error in judgment about buying something you didn't check out. Big difference. ;)
