Hello, I returned my 2010 MBA last friday, and I've been following the package via TNT's website all the way, and it arrived at the Return Center today. It now says 'Goods receipt 01 August' on my status page, what does that mean? And how long til' I get my refund? Also, I didn't wipe the computer clean before I sent it, is that required? I'm a little concerned about this... Thanks.
