The way I see so many people go about shoplifting is wrong, or involves missed opportunities, in my opinion. For beginners I wouldn't generally recommend repeats, but my philosophy is If you find a good place, make the most of it!
It depends on the place of course. For t*rg3t I would NEVER repeat, or at least space it out by a year or longer. But some stores are too good to pass up. In fact, I would argue that it's safer to repeat certain locations than to explore uncharted territory and end up in unfamiliar situations looking nervous, not knowing your escape route.
There's a saying, it goes "a man can never step in the same river twice, because it is not the same river, and he is not the same man". Very wise words. Whenever I go back to the same place, I make sure to disguise myself. Did I prance in there last time, with blue shirt and bright sneakers, then lift from the electronics section? Then next time I'll slouch in there, looking depressed, wearing heavy clothes and boots, then lift from the razor section.
Take advantage of my advice while you still can, while it still makes sense to wear masks.
