Lol, I never thought of thatI only save rares and gems at this point, and I've spent $40 on upgraded stash tabs. One light bulb moment I had was this: I have a least 2 stash tabs worth of gems, I just started putting them in the sockets of armor I had, voila.I fully intend to buy extra tabs (just to support the game) but I am well into Act 2 in cruel and have played around 75 hours or so and have not needed the extra tabs yet. You will soon see that the vast vast majority of whites and blues are not worth picking up.I'm just worried about picking up junk off the beach without hitting town every 5 kills.
You probably won't need to spend $20 if you don't want. Spending $10 will get you 3 more tabs for your stash.
