Sigh. Why do I allow myself to be sucked into things like this?
First, there is no such thing as free shipping. The post office, UPS, FedEx, flying monkeys, whatever ALL charge to ship a package to your house. Somewhere, you have to pay for it. Either in increased product cost, or subscription fees like Amazon Prime, or both (like Amazon).
Second, even if 2 cams fit in the same box that they ship one in, it still weighs more, and package carriers generally charge businesses by weight and size, not just by package size.
Third, and the point nobody else mentioned - Wyze charges a fee for :shipping and handling", not just shipping. Even IF the shipping company charged the same amount to ship one item or 5, someone STILL had to pull 5 different items off the shelf, package them, adjust and restock the shelf, order more, etc. There is some amount of labor involved with each item besides shipping the box.
Wyze is being extremely up front and honest about what and where your costs are when you buy from them.
