That's one way to do it Which is good for me. I will go get the money now and add you. Do I just go up to Felicity and talk to her? haha I have never bought a villager before sorry
I've opened my gates, and yup, just keep talking to her until she suggests moving into your town, and then the next day she'll move into your town. Just make sure you have 9 or less when you come by!
EDIT:
Thank you! You were lovely! Hope you enjoy her!
