I bought a huge collectables bag from the ddo store a long time ago. Pretty much when the store first opened. I'm thrilled with the purchase with one slight problem. It's now filling up. I'll probably have to suck it up and buy a new bag, but I'd like to be able to upgrade my huge store-bought bag to the gargantuan bag that I do not believe was available when I purchased my bag. Maybe charge the difference in tp cost of the 2 bags, plus a little extra for turbine. Thoughts?
