In my area, the Best Buy is ALWAYS offered at $200. To me, that's worth it for a whole day. But the reviews I've read on here about that audit scare the crap out of me. I actually went through with my drug test and background check, paid over $60 with the promise of reimbursement after the first one, took a day off my full time job to do it, spent 2 hours studying and passing the qualifying test, and never heard from the scheduler. Found out later that scheduler quit. I have never decided to try it again, even though I'd get my $60 some bucks back..
There have also been lots of negative stories about that MSC but besides their long reports, I've never had an issue with them. One time I wasn't paid my promised bonus, and they paid me that within a week. So despite the negative comments on the MSC, that's not what scares me about this audit. It's the Best Buy portion of it, ugh!
Sorry, not trying to turn this into a Best Buy discussion, just putting in my two cents on the audit.
