Quoted from audihere:In PayPal it's interesting how under Activity it shows the entire amount paid, but if you click the down arrow it shows your payment and another payment from eBay Inc. to cover the discount.
I noticed a similar phenomenon. The PayPal payment notification on my phone showed the full payment price whereas the eBay completed auction price listed the 15% discounted payment.
I bought an EM arcade score motor. The time limit of the discount prevented me from procrastinating.
