PayPal has owned BillMeLater (and their many, many credit card accounts, e.g. the Newegg Preferred Account) for several years. In late 2014, they changed the way they reported your payments. Transactions that used to show up as BillMeLater are now listed as PayPal Credit Cons DRS. This is unrelated to buying things on eBay or paying for things with PayPal - these are hopefully payments you made from your bank account to a third party credit card that PayPal now owns.
