@briarycliffs What I’ve discovered (at least for me) is that when you pay using SYWR points along with PayPal, you can’t just pay for shipping alone with PayPal.
During checkout, you first see your estimated total, including the sales tax and shipping cost. Then you apply your points, knocking the cost down to no lower than the shipping cost–or possibly a bit more if your points don’t cover the item(s) plus tax.
Unless your “after points applied” total isn’t at least HALF the original estimated total, when you select to CHANGE payment type (from a credit card), the PayPal option will no longer be there. You have to use a credit card. I’m a tad reluctant to do that, at least with any bank card I own!
However, I’ve found that you can use one of those Visa or Mastercard rewards cards, like the ones issued for all those AB beer rebates, to pay for shipping only. And any little bit remaining on that card you can roll into your Amazon gift card account.
Quite a far stretch from the SYWR glory days of yore!
