That is silly. I’m glad you’ve read through the whole thread to see that I did no such thing.
I don’t know about petty. It’d be petty if I was being a dick about it.
I got a response last night from the seller. He of course didn’t realize the error until I pointed it out to him. He’d have been happy to send me 1B, but couldn’t get his hands on a copy (that wasn’t $15), so instead offered a $2 discount (or a refund if I wanted to return them all). All I asked was that he send me an e-mail if he manages to track down a copy and give me a chance to buy it.
