Punchy's Return?

MTS storage is the same as before??
5k mesos a piece.. put them each at 221 NX.. and they stays forevers?

Indeed, but the tax put on the items you sell is 500 nx these days, so if you put something up at min. amount it'll be 600 something for buyers.
Here's what you do to use MTS as a storage though:
Put your items up for 24312343124 nx and when you've done that, immediately cancel the sale and the item end up in your transfer list. Voila, permanent storage for 5k mesos.
