I got an E-mail today from Personna saying that they now have an online store and have free shipping. Might be worth checking out
The prices seem a bit higher than the stores.
Probably to cover shipping
Well, I have to take that back. I went to buy some new M5 blades last night and they cost me about $1 more than they price on the site. They mus be getting more popular since I used to be able to get them for less than $4 for a pack of 4.
I'm tempted to order from them because the have things that I can't find locally.
