How to sell a lot of invites/accounts, here is my secret...

1.Have many trackers/invites/accounts - minimum amount is 10 trackers, and at least 1 must be a very good tracker like TL or bitmetv/bitme/scc/trancetraffic/etc
2.Have very requested trackers
3.Sell cheap, or very cheap...
4.accept paypal or moneybookers or different payment methods (the more the better) but paypal is a must.
5.Talk nice with the people who buy, give them feedback always, and explain them everything they need to know about the tracker and stuff not to get disabled
6.Always keep a history of all you sell, and if someone's invite or account gets disabled refund him the money. This will increase your reputation with the buyers, and they will recommend their friends to buy from you.
7.Make sure the people you sell invites to are not from banned country
8.Always tell them to give you feedback.
9. Make trades and try get as many trackers as possible by signing up on any tracker that is open
10.Be helpful on the forum, make tutorials, don't talk bad about anyone(anyone can be potential buyer), give advices
11.Become trusted seller or VIP member
12.Advertise torrentinvites.org(aka spam it) anywhere you can think of (be careful, trackers admin will ban you for this)... you can spam the link in filesharefreak comments, etc...
13. Check buyers section and try to get those trackers, probably nobody on the forum has them... so if you have those people will buy only from you
14. Make some giveaways, this will make the people like you and probably buy from you in the future
15.Check how other trusted sellers threads look like and copy them, put trackers on categoryes, alphabetically, or just nicely on the page

If anyone else has any advices on how to sell many trackers feel free post reply

I did all above and I sold many invites/accounts etc.
The most important is to sell cheap and have many trackers, the rest is not so important, but worth taking into consideration if you want to sell many trackers.
