D. - good for you!!! I am the same way - I carry them in my purse until I have a few and then drop them off - I used to go to Walgreens but I think they have stopped that - I did find Home Depot does have a program but many of their employee dont know about it - go to the service desk and ask - good luck and congrats on the 3 month old baby boy - what part of chicago are you from?
