I just went there today and picked up 15 packs! Guess that'll last me a while! Last couple times I went in there they were out. At that price ($1.49/2 pack) I would have ordered them on-line and paid for shipping if they were out again. Now I won't feel guilty for changing blades whenever I need to. Thanks for the tip!! They are never advertised in the HF flyers we get in the Sunday papers.
