So rather than buying the copies directly for ~$10-11, I'm planning on buying items off the Steam market, handing out $11 worth of Steam items per person (yes I know I must calculate steam's fees too), and having them buy the game, and send the extra inventory copy of DST back to me. I might take a slight loss in profits, but I figure it doesn't matter too much, so long as I get all the copies or items back

I was thinking CSGO keys for the items, since they seem to be standard, but then I remembered:
CSGO keys go from $2.50 to about $2.20 around Christmas time. If anyone has an item/set of items they recommend, let me know please. And if you want DST, but don't know if you qualify, or are confused by the steps, let me know.
To sum it up, you get a copy of DST for free, if I choose you, but it takes some effort. Hope I posted in the right forum, I wasn't 100% sure.
