I ordered a box of boxes from The Packaging Wholesalers via Amazon.ca
Hilariously, there's no way anymore to get help from any "real" person over at Amazon anymore, even for Prime members. I've gotten all kinds of weird stuff shipped to me, including a $12,000 server motherboard once, which Amazon told me I was free to keep as they would ship out the $124 SSD I ordered. I insisted that I return it, and after much hassle over several weeks, I was finally able get ahold of a non-chatbot, non-foreign service rep that finally took the time to listen and sent me a return label. Since I finally got ahold of someone real, I remarked this is the last time I go through such a hassle to return their property because of the way they treated me when I was trying to do them a favor.
