I thought it might be usefull to start a forum to discuss item selling prices.
We don't want to lose lots of money when we sell items for half the price we should sell it at, as well as we hate to spend lots of time with useless items because we try to sell them for a way too high price.

Since I got rich of buying and selling stuff, I wrote down some items and prices I managed to sell the items at.
So here we go:

Sunstone
1,8m / 2m

Moonstone
1,5m / 1,7m

Activition
500k

Refresher hold
300k

Bull hamstern
300k

Egg (depends on exp.)
0% 200k / 300k
99% 7m / 10m

Enatale sword
400k / 500k

I don't know if these are the right prices by your opinions, so correct me if u think im wrong.
