I was digging thru a dusty box at a LGS and found a set of used J frame grips for $10. SWEET!!! Been looking for a set.

Also in the box was a S&W magazine, in original packaging, for the CS40. Asking price was $15. They also had a used S&W 4516-1 mag for $5. 3-4 sets of aftermarket 39 grip panels in fancy wood for $5 a set.

I neither have, nor will I probably ever buy, any of those guns.

The question is... Should I be buying cheap things like these to flip for a profit or is it wasted effort? If the CS40 mag could be sold for $40 without too much effort, that seems to make sense.
Not looking to take advantage of anyone, but if the shop wants to sell these things cheap just to move 'em out, I could oblige.

Opinions are appreciated.
