Seth,
I've only ordered from them once. But it was a no hassle experience. I bought 3 cases of 750's from them. Everything went fine. Had I not found my local source a mere 4 miles from my house, I'd still be ordering from them. I did find that it pays to play with the quantities though. You might be able to get 2 cases shipped for $20, but adding a third case may not increase shipping at all. So, look at different quantities - there may be a "sweet spot" that will make shipping a little easier to bear.
