It used to be possible to get some cheap widgets on Aliexpress for $1. Even if you assume that the widget is "free", $1 seems like a great rate for shipping. Do bulk rates in the US compare with that?
Many years ago it was possible, not recently. UPU rates used to be lower before 2015 or so.
Also, for small, light products, it's absolutely possible to ship below $1. Full 5-digit pre-sorting and injection for a 1 oz flat costs 43 cents to deliver currently. Presorting but with no injection costs 81 cents.
