A lot of the accessories included in that kit are throwaways at best. $9500 for what's offered is highway robbery. Take the 7D body and run!
When I saw that BigValueInc. was the vendor, my sense of surprise was immediately dispelled. These guys are known for shady dealings and have very questionable customer service (check the eBay feedback and do a Google search of them through the BBB). Lest we forget the "Great 5D Mark III Fiasco of Thanksgiving, 2012?" That's how I learned my lesson when dealing with these guys.
As has been pointed out, while morally ambiguous, the deal is perfectly legal.
