£60 for 3 months, just to message people who are also willing to pay that much for the possibility of a date? Seems a bit steep.
Anyway, met my fiancée online. Not on a dating site though, but online at first. She's also American and I've just had my visa approved to fly out there and get married, so pretty different situation, but just to say online can work.
I don't have any personal experience with dating sites, but my dad used them a lot, worked out pretty well for him. Not sure if he used paid or free ones, never really felt like asking my dad about his dating life.
