I know cookies are a thing, but how do they know I’ve been on other sites? My reason for asking is that the last time I visited Groupon I received a coupon in my email for $5 off. Today I visited 1800flowers and got a PayPal coupon from them. I don’t have a PayPal app or anything, so how do they know I’ve been on groupon?

Those cookies are shared on services that feed PayPal, ebay, Amazon, google, Facebook, etc etc. While not all of those companies share the same singular service, the big ones, Amazon, google, Facebook, are enough of a coverage that your browsing activities are trackable
Ummm care to rephrase you case? Sounds like you got a coupon from Groupon and another one from 1800,. I don’t see what link you’re talking about. 800flowers sent you a Paypal coupon? Not a Groupon?
