Luke, I've always heard that when it comes to high value cards, "you can never pay too much, you can only pay it too soon." Meaning that you may have overpaid for that card today, but it will increase in value. The good cards like that one always do, and will soon be worth more than you paid for it.
I use that theory to justify my purchases, and even if it doesn't always work, it does always make me feel better.
And that's a great Matty.
