Slow USPS is one thing, not providing a tracking number is another. I always provide tracking weather is a set of dies or a $3000 rifle. Tracking should always be requested and provided. After that, we are all at the mercy of the shipping company be it USPS, UPS, or whoever. I did a transfer for a guy once who bought a high end shotgun via GB and he never relaxed until he picked it up. No tracking was provided to him and the seller didn't communicate. He was a wreck. I pretty much told him never again, not worth the $25 transfer fee. In the end he received a very nice shotgun and it all worked out. Some of these sellers are just not in a hurry to ship and could do better.
