alt Hacker NewsI've used something like this list to get "over the hump" for $35 to reach free shipping without prime.
It's horribly annoying to have a product that is $34.99 and you want it, but it'll cost shipping unless you get the damn Volkswagen screw; and then Amazon ships them individually anyway.
Just play their stupid game. My wife does this all the time, buys random items just to go past the free shipping range, then the item goes into trash (or is returned, if possible).
Even sellers started doing this, but instead of selling random items, they sell "extra hardened packaging material" conveniently at $1, $2, $3... prices. Of course when item arrives, no extra material to be seen. When questioned, one of them said "well, the package had cardboard box - that's it, wink wink, please do not report us".
