Able sisters shop

[CuddleThePumpkin]

Can someone give me details on how to get the Able sisters shop. I have the museum, nooks cranny (have spoken to Mable there too) Tom Nook is currently upgrading his tent, it will be done tomorrow. Mable is currently in my Plaza and I have bought 1 of everything from her which I am sure has gone over 5000 bells. Will she say she is going to open up shop or will it randomly just happen?
Many thanks.

I'm not 100% sure but I think you need to buy at least 5 items, total worth 5000 bells+, and once you have done that, you must wait until the next time she shows, which should be in a couple of days.

Answer from someone who don't have them yet, but I read that you had to buy from Mabel three different days.
