Since I only get here between shifts I miss alot of stuff ( like Glitchmas etc) . I have just got back and I noticed that you can now give bags to other players. These inventory bags also travel with the content (tested). So you could sell a bag full of x,y,z, to any one with negotiated prices.
I haven't tested the mailing of inventory bags yet , might do that when the servers are back up. But this is a bit of a plus for moving large quantities of gear or a mixed assortment to new players.
Unable to do a bag of items via the Auction site yet as you can not list its contents. I think this has potential .
