Yeah I love Natchezss.com, but the shipping charges keep me from ordering from unless I'm buying a lot at once. The problem is that many of the other online stores like Midway charge just as much shipping, and have higher prices. The exception seems to be Grafs. They have higher prices, but cheaper shipping. Powder Valley also has cheaper prices on some stuff, so I also order from them some.
However, compared to local shops most of the time even buying just one or two items from Natchez more than pays for the shipping.
What I do is add everything I want to the cart and see what the total will be with shipping. I check this at a few sites and go with the place that's the cheapest overall. If I'm ordering $100 or more, it's usually Natchez or Powder Valley. If I'm ordering $50 or so worth sometimes Grafs is the cheapest.
