I think there are a few good ideas on this, and it would not be hard to hybrid them. For instance, the fourth option labled 'Buy from Player' or what have you would be good, but instead of the shop being a seperate place/out of the bank/in your inventory, make it a seperate tab on the HUD. Almost like an inventory add-on, with all items stackable, and set prices on them. And, maybe have it start off as only being able to hold one, and pay gold to someone (maybe a bank teller) to upgrade the size of it. Each size upgrade costing progressivly more. And , of course, miners would love to do this to store extra ore, so possibly a limit should be put on it, like you must leave an item for sale atleast 24 hours before removing it, and it be mandatory for any item in the shop to have a price, and also that there be some way to keep the priced from being outrageous...maybe like no more then twice RS's estimated value of the item...Anyway, just spit-balling ideas, and I'll conclude with a shop would be a lovely way to sell items, the current system S:idea::idea::idea:S.
