Link to when this deal was posted last year:
I like these sets as they have a good number of C and D adapters and have nice hard cases to store them all. My battery strategy was to buy as many of these combo's as I thought I'd need C's and D's and then later I'll buy more AA and AAA on sale as needed. Once you take out a few C or D's, there's plenty of room in the cases for extra batteries later.
