If you buy a card for $1 (0.75 +0.25 shipping) and then sell it for $0.90, you get $0.90. You paid 10 cents of the buyer's shipping. Very kind of you.
If you buy the card for $1 and list it for .90, the buyer will be paying 1.15. You would make .15, because you have already paid the shipping. COMC deposits the future shipping into your account
