Most place that have what (I would assume) you consider acceptable shipping charges are just pushing the charges into the cost of the inventory. I ordered a complete reloading kit with turret press, extra dies, primer feeder, etc...it cost me about $15 for shipping and it was at my door in about 3 days. That's right around regular UPS pricing.

I just did a comparison between Brownell's and Midway. It was hard to find the same item on both sites but I did find this...
"Aimpoint Micro T-1 Tactical Red Dot Sight 4 MOA with Picatinny-Style Mount Matte" Price is $633 on both sites. Midway's shipping is $7.93 and Brownell's is $11.95 for the same product, and both ground shipping.
