Brandclub Legit?

I've been trying to decide if I want to try Brandclub. Anyone here use Brandclub? Do you recommend it? I know you get rewards from Walmart, Target, Amazon, and Chewy. Can someone please tell me if Brandclub works with any other stores? Such as Kroger, CVS, Walgreens, Randall's, or Petsmart? Thank you in advance for replies.
