Selling for ridiculously high amounts

[CYoung187]

Retainers get a large tax write off if their stuff doesn't sell for a long time.

It provides up to 80 slots of additional storage when needed. And if someone actually buys it, major profit.

I been thinking that its a great way to store peisteskinmaps. I also send tem as mail to a friend so when we have about 20+ we take a day and just do them all at once

I put my unhidden map on my retainer for sale at 500K which was double the next highest price, so I can have some time to think about when and if I want to use them. After a couple of weeks I forgot about them, and then boom they actually sold. Oh well can't complain there. I bank my peiste maps there for 125K too.
