There are people who say a dollar isn’t worth much anymore. I say it all depends on where you shop.
I bought this group of books today at the used book store. Had I bought them new they would have cost me approximately $65+. At the stores ‘used’ prices they added up to just over $20. Because I took in stack of my own used books I got $19.75 in store credit and ended up paying 75 cents for the lot. And the really cool part is when I’m through with them I’ll take them back and get store credit for them to use for more.
