Yes you can sell here.
1. first thing to do is move all the cards you want to sell to FS/FT list. That way they will show up on other members list if there are a match. Then they may come to you. You will also see all the members that have the cards on their want list. (Per match alerts)
2. note in your profile that you are Only selling. If you are only selling.
3. do a posting now and then. Maybe with a few items not on the list or highlight some cards. Do not over do the postings.
4. Price fairly when you make or get offers. I let the buyers set the price as I'm closer to the point of just dumping cards vs making money on them.
5. Communiation is the key.
Most members prefer to trade as they have a ton of cards, they want to get rid of also.
