Lol sell meso I understand
How to even sell item.
You list cheap, ask buyer camp, but the timing that your item gets listed is totally random. Very high chance tio kio away.
Can be done safely if you have the mesos to cover the value of what you are selling
1. Buyer sells you a cheap item for the value of the real item, say 100,000,000 mesos. Money is now with the buyer as collateral in case you do not complete trade, or someone else buys the item before the trade is complete. Either way, you are paid at this stage.
2. You list the real item for 90,000,000 mesos (minus tax)
3. Buyer buys real item for 90,000,000 mesos. You get back 81,000,000 mesos.
The tax value is generally considered operating cost.
