Selling is the hardest part after restocking. I can provide some tips from my own experience:
- Create a new trade for the object every day, ''online daily or posted x date'' in the description somehow helps cause people will expect a quick respond
- Say you are willing to haggle
- Advertise in the trading chat or avatar chat if you are selling stuff related to avys
- Be patient.
If you feel the urge to quick get neopoints then sell to resellers, who sometimes post in the trading chat asking to buy with pure, but expect to sell your object 40-50% off (which isn't so bad considering you get it ilegit).
Hope this help in some way
