I've been subscribed to Sponge Club for 4 months now and it's really great. I always forget to buy sponges and use the same disgusting sponge for way too long. Now when my sponges are getting even a little grody, I just walk out to the mailbox and grab the new ones. Changed my address once and it was super easy, if that counts for anything. Would recommend. Also, They come with 2 of each color so you can keep track of floor/bathroom sponge vs food surface sponge.
