I haven't documented all of the times QSC has screwed someone over but the folks over at Peppy's have been monitoring their behavior closely and actually have a warning
on their vendor page.
Domestic vendors absolutely charge a premium but they also take very good care of their customers. I have first hand experience with that. USPS marked one of my packages from Skye as delivered without dropping off the box and I was really upset because that order wasn't cheap. I reached out to them and not only were they super nice, they promised to reship the package if it wasn't delivered within a few days. I waited and the box was ultimately delivered, but that kind of support is worth its weight in gold.
