Yes, I can see now that I was jumping at shadows, thinking that because larger sites no longer require a paypal account to buy with, that might reduce the number of buyers here able to use paypal at the checkout.
I haven't kept up with how card payment has developed since 2012 when I first started buying on-line. Because I've usually got a cash balance in my paypal account and always have cash in the back-up bank account, it's something I rarely do. These days I guess it's more the norm for people to use paypal / card than paypal balance / bank account.
Must try to keep up!!
