I have designated on my PayPal the method of payment I prefer for purchases and auctions.  So, I thought PayPal would deduct money from that account to pay a merchant when I pay via PayPal.  However, in the past week, about 5 of my purchases which include grocery deliver, medical supplies from EBay, and merchandise from EBay have been routed to my personal checking account.  Now, my checking account is overdrawn. I have talked to the merchants, my bank, and PayPal.  PayPal says that somehow, despite what I have set, they route a purchase to a different funding source if I have made a previous purchase from the merchants.  As best I can tell, they have internally set up what they call “autopay.”  I am soooo upset.
