Dollyhair have a reputation for being slow, but I bought some hair from them recently (I am in the UK) and it came very promptly considering the distance involved with no issues or errors. I was anticipating I wouldn't be able to begin rooting Lala till August but the hair was here waiting for me when I came home from uni (so I think 10 days-2 weeks max?)
So I would also try there if it's a specific colour match? If I remember right postage was about $6.
