Musician’s Friend has a 3 pack of D’Addario string sets for $13.99. These are all 10 gauge sets.
Set 1: NYXL (NYXL1046) these are $12.99 anywhere you look anyway.
Set 2: XL 10 gauge (EXL110). These are D’Addario’s "regular" strings. Retail for about $5
Set 3: XL Balanced Tension (EXL110BT). I don’t know much about these but I’ll give them a shot. Retail for about $5
Throw in some guitar picks (you can never have too many) and this is a pretty decent deal for 3 sets of strings.
