They're double potted. I tried taking one to the register w/o the white cache pot and that didn't work. (Giggle!) Don't bother. They are decent cache pots but I would like to have the option to purchase without. $20 is about $5 too much for me for a houseplant. I'll wait to find something smaller at a smaller price or just not have that one. ...unless it's a Begonia, Adenium, Plectranthus, or Kalanchoe that I don't already have.
I have found a few on clearance when they get thirsty. As said, they aren't getting watered, so if you visit often, you might find one that's still OK but just needs a drink.
