Stick, I am not insulted and I don't feel like you are being critical. I want this feedback so I can make improvements to my system. I am still quite new to the tool selling game, so I am sure I have a lot to improve upon.
I am afraid of the cardboard bubble-mailers because of the delicateness some of you are describing. I have sent a few tools (including yours, Hiball) in one of those plastic bubble mailers. It's not Tyvek, but another somewhat similar material that is not supposed to tear. Problem is that they are pretty damned expensive at the local Staples.
This all has me thinking. What about insurance when using the USPS? Buyers always want the cheapest shipping. Sometimes, they feel that flat rate Priority is too high, so they ask you to look for alternatives to save a buck or two. I always like to get Delivery Confirmation so there is a tracking number for the package. But how many of you get insurance for EVERY tool you ship? Do you make the buyer pay for it? It adds another what, $1.50 or so to the cost, and once you have the fee to mail, Delivery Confirmation, and insurance, the $15 ratchet you are trying to sell has bloated to around $22+ shipped.
