I received the large order from PBR a while back, and have been slowly using up the parts in the restoration of my pins. There was one error in what was shipped (the caps for the Power Play were 100 points, instead of the 1000 points they should have been).
Steve at PBR was excellent in handling this, and promptly shipped the correct ones in a second shipment. The postage for the 3 caps (even though of course I wasn't charged this) came to $3.46. The postage for the entire order (and it was fairly sizeable) came to about $65, more than reasonable for its size and weight.
Just another small note to say that I would not hesitate to recommend Steve Young at PBR. Very reasonable postage rates, big or small packages.
