Mail order Pipes?

I very rarely purchase a new pipe. I have 20, not counting the cobs in the shop, shed, camera bag, etc. The only decent tobacconist in Anchorage closed a few years ago. I did buy a Millville from the maker while in London a few months ago and another silver cap from Peterson while in Dublin.
So, the question is: How does one select a pipe that "fits" and feels right in the mouth and hand, is unblemished, well fitted and finished without ever actually eye-balling and fondling the pipe? It's an impulse purchase for me. I walk into a shop and look over the inventory. If I see a shape and size that is appealing to my eye I ask to see it and check the fittings, finish, weight, etc. If I can't turn it loose I'll part with some money and hope that I got a good smoker.
Do retailers and independent carvers willingly accept returns due to a pipe not meeting expectations? Unsmoked of course! Or, is it strictly a "buyer beware" thing?

I appreciate the input. It's often times next impossible to spot a fill when the pipe is in your hand, much less when viewing a jpg on a computer screen.
I guess what I'm getting at is what's the criteria on-line buyers use to determine whether or not to purchase a particular pipe. I'm pretty sure Kevin, Iwan Ries, would readily accept a return or 2 or 3, if I was not happy with a purchase. I've been a customer, on and off, for years. But would not a seller soon become exasperated with me should I return five or six before I was satisfied?
Obviously many people have no problem with buying a pipe, un-fondled and basically sight unseen. There's a large, successful market on-line so maybe it's just my prejudice. I just can't get my mind around the idea.
