I go to two local stores, one the same one as Funzy12 (about 45 minutes) and another about the same distance in the opposite direction. With the knives I buy from them, I pay about 30-40% more than I'd pay online, but I can get it RIGHT THEN. One pays for convenience. No waiting on a knife to arrive, which slows down time like a science-fiction novel in my case!
The other store charges full retail. It is primarily a gun shop first and knives are far secondary. I go there to handle knives I've researched online, then buy then online. I have completed some impulse buys there, because at just HAD to have it right then, but generally do not pay retail when I can get them online so much cheaper.
I have also bought a couple of knives there, took them home, and played with them (but never used them at all) while going ahead and purchasing the same one online. When my online one gets here, I return the locally-bought one that charges full retail. I'm "borrowing" it in essence, but I treat it as not mine in the meantime, meaning very carefully. With this shop, knives are probably 2% of their business, are a good-sized operation so I am not hurting them by doing so. But I've only done that twice in three years.
One good thing about getting them at the local store is you can examine THE actual knife you will add to your life. Fit and finish, blade centering, etc. are not a question, you're looking right at it. Remember, these are production items. Things vary with some makers, others are much more controlled in what goes out the door. I've had to send back and swap out several knives from online sources because of quality control issues. I've also passed up knives at the second retailer because their quality was not up to par; if they had arrived from an online source, they would have been in the mail that day going back to be swapped out. Don't have to do that if it is in your hand.
So call ahead and get their price if it is a particular knife you want, and also to make sure they still have it in stock. It sucks to drive that far and it's not there when you get there. Have them put it behind the counter while you drive there. Who knows, you might not really like it when you get there and walk out with something different. That has happened to me on more than one occasion.
Also, it's usually worth the drive when you get there, and if you buy something you get to play with it all the way home!
And lastly, if you have knives that need sharpened, and they offer that service (like River's Edge does, and they do a great job very inexpensively) bring those with you and get them done at the same time.
