Yeah, I've read many an article on how terrible USPS is doing. That sounds about right. Those boxes I got are what I was expecting on mailing all along, they offer much more protection than envelopes and yeah, I'll be stuffing them with some sort of padding as well. I may do envelopes for this group buy, I did only ask for 100 boxes lol. The boxes hold more keys though (more useful for the Portal GB,) and are sturdier. I suppose I could save you guys a buck if I ordered those envelopes and shipped via them but I'm not sure if it's that big of a deal. You guys tell me. I was going to charge a dollar for the time it takes to pack and ship 100 orders, so $5 or $6 shipping to the US. Seems fair to me, and that's pretty much what most group buys are charging for shipping from what I've seen. Thoughts?
