More stuff for the mall?

I love that damn mall, since it supplies me with potion engredients, but I think that there needs to be more items to buy and sell. I sold all my diamonds and gold, which did load me up, but i don't think people will be very keen on selling all of their diamonds in order to get money. You could probably add some more stories by adding a basement for user-created stalls but I'm not sure how you guys wanna role with it. I do have a great design for maximum buying space with minimal room for you if you need me to show you.
And if that doesn't happen, maybe a flea market where people can buy indecidual chests? I'm not really sure, but we at least should have some more selling power before the non-doners get on.

Cheers erryone!
