I generally figured that if you do a B2G1 with all items at the same price then your cost is 67 cents on the dollar. Then GS just has to pay you > 67% of their sale price across all three games.
For example, if I do a B2G1 on 3 Games that cost $50/each, then the break even is at $100 TIV. But your ROI is 0% if you only get a TIV of $100.
Depends on how you want to make your trade credit? do you want to put up $1 to make $1,000? Or do you want to put up $10,000,000 to make $1,000,000? What's more important ROI? or net gains?
Which is better, doing a B2G1 for $100 for TIV of $150? Or doing a B2G1 for $20 for TIV of $40?
It's just a chocolate or vanilla question. Everybody's answer will be different.
