Rebecca, ITA and good for you!
I am addicted to cloth bags for grocery shopping - the only problem has been for absent-minded me to be sure I have the bags with me each time I go grocery shopping.
I got tickled at your towel usage - using them *twice* after each shower? I feel like a slob - I think I change our towels once every few weeks.
I am a diva convert - love love love it. I encourage you to give it a few cycles if it doesn't work really well this first time.
