So I was at the store tonight looking at the Black Friday scraps left over for decidedly-non-Black-Friday reasons, when I saw that they had one copy of Firefly left over for $10. I hemmed and hawwed about picking it up, but in the end, I decided that Amazon would probably have it just as cheap, and I could pick it up at a later date. So I just checked Amazon and apparently the cheapest used copy they have is $15. I has a sad.
Should I have grabbed it? I think I already know the answer.
