What a lovely read. Welcome to the forums! I'm glad you got to take Auri home! Sounds like you were made for each other!
Funnily enough, I first discovered parrots whilst working in a pet store as well. We had a grey and an eclectus in during my time there. I fell in love with Reggie, the electus but wasn't able to take him at that point because I already had Alfie. He had come from another store that hadn't cared for him properly so we got him eating better food, got his feathers back to good condition and socialised him before selling him to a family. I was fascinated by the grey we had in too. So I did loads of research, read every book I could find, talked it through with my family and eventually spent all my savings on getting Alfie from another local pet shop.
