Yep, I don't play the backorder game and I do the same exact thing. If I need something THAT bad, I'll get my local gun store to order it for me and I'll pre-pay. Otherwise, with the online retailers, I just put it on my wish list and wait.
Natchez has THE highest shipping I've ever seen. A young man I'm getting started on reloading bought ONE box of primers from Natchez (that's all he wanted) and aside from the $27.50 HAZMAT fee, which is preset, paid $15.80 for "shipping and handling."
I've never ordered from Natchez, but that right there ensures that I never will.
In the past few years, I've seen Midway's shipping actually seem to come down while their shipping speed has increased. But mainly, I like Potterfield's stance on not gouging, not jacking up prices and not doing business with LE/gov't agencies in communist states. That alone will keep a healthy portion of my online business going to Midway.
