tdgeek: Isn't it easier to just go to Youbee and walk away (in 30 seconds :-). ). With your replaced adapters. I agree with Jase I think it was, why do it online?
I suppose not everyone lives near a Yoobee (or other Apple Authorised Service Provider) or some people (hermits?) simply don't like face-to-face interactions.
Or some may struggle to get to an AASP within their opening hours.
