I can proxy if you'd be kind enough to lend packing and procedure advice nubbinator.
EDIT: Only if the rest of the US orderers think it will be worth it.
Packing advice:
1. Did you use enough padding/bubblewrap/packaging material? If you said no, add more. If you said yes, add more.
2. This fits perfectly in this box! No it doesn't. Unless the person isn't willing to spend a little more on a bigger box for more packaging, the box is too small if it just fits. If the PCB touches both ends of the box or is with 1/8", the box is too small.
3. Surely this PCB will be fine just in bubble wrap, right? No. With smaller PCBs, it can be, but with a 60% or bigger, always wrap it in bubble wrap, sandwich it between some cardboard, and wrap some more.
4. Voids in packaging are fine, right? I mean, I have all this bubblewrap and other packaging to protect it. No, you don't. It can be peanuts, wadded up newspaper, whatever, the stuff shouldn't be able to bang around in the package. Shifting is okay, not full on moving.
Procedure advice:
1. Ship, at minimum, USPS Priority. No First Class, no Parcel Post.
2. Collect money via Paypal and buy shipping through Paypal.
3. Offer shipping insurance at the going rate if they want it. Explicitly state in the invoice that you are not responsible for any damaged or property lost in transit if they do not pay extra for the shipping insurance except in cases of negligence.
4. Document everything. Show how you packed it and shipped it.
It sounds scary, but it really isn't if you take the time to do it right.
Not sure I'm comfortable with a proxy :/
You should be able to have it shipped direct to you. There were a few last time with the Butterfly pad. It's a little more expensive, but it can be done.
