Pincushion Plant

I noticed that Wally World has a bunch of pincushion plants on sale. I also noticed that they have some not on sale(almost 2x the $ of the ones on sale). They are in 2 different conditions-stressed and blooming.
They are in different sized pots also , so I don’t know if the sale batch(in the larger pots) came in in a stressed condition or they got that way. Anyway, I don’t want to buy a ‘pig in a poke’, but I do like a bargain, and would like to know what signs to look for in buying a ‘stressed’ plant that would indicate it has a chance of rallying.
Thanks !
