PayPal emailed me this morning and included a link simply saying “PayPal on Facebook”.
I clicked through to see if magic laid behind it, but sadly it didn’t. They post the occasional articles with exciting titles like, “Are cheques worth fighting for?” (answer, no - they’re also not worth writing articles about).
PayPal also post a lot of deals and offers, but they’re usually just that you can save 20% on this website today if you pay with PayPal. Fairly mild as prompts go, but perhaps worth keeping an eye out to see if a website you’re already intending to buy from pops up.
