If everyone purchased their knives at B&M stores the result would be a lower price at the B&M. This won't happen because B&M stores have to pay rent. You can haggle, but they
really do have higher costs.
Like david415, I have been on both sides of the counter, I can see both sides. Unfortunatly, in my area there , there is only one knife outlet with four or five stores. Because the compitition is only a few sporting goods stores, they are free to charge what they like.
While I would like to patronize the B&M stores, I can not see paying 50-100% more for a knife than I need to (a BM940 goes for almost $200). So I go into the store, don't ask any questions and fondle the knives.
Buying knives on the www is not without its own dangers, you can not hold the knife and unless you know exactly what you are looking for, the pics can be deceptive.
I have been lucky. I have never sent a knife back, my limited research at the local stores helped...along with the few good pics on the www. I have been a little surprised, yes...some things came a little bigger...or smaller...but nothing too far out of line.
All the local knife stores are in malls and I have to force myself to go there (used to be only at xmas), so between this and the prices, I have little choice.
Hoping for a better future...
