Secretly A Pony

Ugh! I cannot do restocking! I get some small good deals, but I continually miss the big ones, even in the "beginner" shops, and waiting around for the shop(s) I want to restock so I can try again is causing me more frustration than profit. I know anything that's not games requires patience. It's that I have to wait around, doing little things while minding the clock that's wearing my patience thin. I make more profit finding deals (snipes?) on the Super Shop Wizard (by the way, that is the best perk of premium, hands down!). I've heard of people making several thousands or making millions from the stock market, but it seems my skills don't lie there either. Anything from the battledome is out because my pet is too weak at the moment. I seem to do well with the food club because I've won so far on the few bets I've made. I already play the mobile app, but that caps out at 50K. Yes, that's a lot on its own (to me anyway), but I don't want to stop there. So, what's everyone's big profit maker and how do you do it?
