Unlikely, but if you consider your free time worth nothing, "Perhaps".
The thing is that you're never going to get 100% of MSRP. For example, a $99 copy of Keynote typically closes on eBay for $45...that's 50% of MSRP. Personally, if I can pay 10% more and get something from the OEM instead of via eBay, I'll usually pay the extra, as the potentially avoided hassles are worth it to me; YMMV.
FWIW, I already have too many "spares" of certain things - - anyone want a pair of 8500 AV's? ..or 4-5 ADB keyboards? Its worth less than its cost of shipping, but I still can't bear to throw it out, like a....mere...PC.
