Ok. Possibly a real newb question here I see items on vendors for 175 million, 250 million... uber rares naturally. How do you buy that? I assume my bank holds say 125 items. Although I think I have a couple up grades on that. So if I can only get 125 million dollar checks or even 160 (whatever the max is). How do you buy these things? Been bothering me for awhile lol. Thx!
