..this is why you don't walk around picking up random stuff on members servers and banking it?
i used to walk around and pick up random things on my main. when i was off members i had like 100 / 75 f2p items and like 200 mem items that were utter stuff.
also i don't do combat anymore so i wouldn't know 
i clean my bank a lot, i usually end up with a lot of stuff that i don't need, IE seeds, farming supplies, handicapped dwarf axe stuff, ect. even when i do clean my bank out, i still have like four different sets of armor + different boots/helms/assorted underwear as well as about 30 weapons and shields. i also tend to have a forgetload of costume items, food, potions, gems, and stuff like that. i always pick things up and intend to sell them, but with the lack of a reliable way to sell things i accumulate things. it's like the rpg kleptomania where you pick stuff up to pawn to the general store, only the general store is handicapped and pays 30 coins for something you could sell for 100k on the GE.
