Need to order other things to make up about $ 50 total for free
shipping. As my wife likes certain Yuban Gold coffee that is not in
the local stores any more, I ordered lots of that and the 99% for the
free shipping.

It seems to be 99% as I put equal ammounts of that and some Walmart 90%
in some open containers (about half a teaspoon) and kept checking on it.
The 90% still had something left in it after all the 99% was gone or
almost gone.

Thanks for the link Ralph! I don't normally buy from Amazon so shipping adds up, but my sister buys there all the time, so I have her get select items for me.
