Arrrrgh! That is a GREAT deal.
You are right again, that's exactly how you have to look at it. Win many, loose a few. However, when you overpay think of it as not paying too much, just buying too soon.
A friend, who is very knowledgeable about M1 Carbines, and on this site often, counseled me when I agonized over paying too much for a Carbine. He told me if you collect, you’ll make mistakes. He said that I should relax and wait. If the piece is right, the value will almost always overtake the purchase.
He’s right!
