7.62X39 is still very cheap. Less than $5 a box of 20 at CheaperThanDirt(dot)com. Not reloadable, but you can buy more than you can carry for just a few Benjamins.
That’s the ONLY thing cheap at CTD. I went into one of the stores yesterday. Everything is still more expensive, some things by a large margin, than your LGS.
