Scammers are trying all new kinds of schemes. I recently got a legitimate email from Paypal saying that I had an invoice from someone, and to click a link to verify it. I did NOT click the link thinking it was directly from a scammer. Instead, I logged into my Paypal account, and there was indeed an invoice requesting payment of $699.99. It waslaughingly enough from someone named “scammer something...” I refused the charge on Paypal’s official site. If it had been something smaller, and with a more official sounding name, I may not have been so wary.
I got that same PayPal scam, with someone with a Yahoo email address claiming I ordered Microsoft Office for $299. I notified PayPal, but they were useless. I canceled their request for $$$ and called it a day.
