Pretty done with buying NBA 2K22 MT/VC. mmoball.com seems to be the cheapest I can find. Anyone have experience with them or know other cheaper and reliable places to buy?

You should ask this in an NBA 2K or a MyTeam discord server. Not on the speedrunning forums, we know nothing about buying MT my man.

You can go to NBA2king to see, maybe it is a good choice.
