I have a website for which customers pay an automatic monthly subscription fee through PayPal for access.
The standard cost for access is $19 and the cost for more features is $29.
For the past several years PayPal has been taking an 85 cent cut out of the $19 and $1.14 cut from the $29. These are fine because it these cuts are indeed PayPal's proper advertised cut of 2.9% + 30 cents.
What I have been noticing however, on several payments in the last month or so (haven't checked how far back it goes) the cut for $19 payments has been $1.14 – exactly 6% and (coincidentally or not) the exact same as the $29 cut.
What the fuck is going on here?
