Second, the weather seal/ rubber gasket towards the mount end doesn't make contact with the camera. I don't see what purpose it serves if it doesn't. Is it supposed to?
The only thought I've had so far is to see if perhaps Best Buy will allow me to take a few snaps with their floor model of the lens, and then duplicating those shots with my copy. Although I have no idea if they'd allow me to do that, especially if they know I already own that model!
Return it to Best Buy for a refund then buy another copy from them. If you were in the UK I'd say DO NOT SEND IT BACK TO CANON as if you're unhappy with any repairs Canon make you can't later on demand a refund or replacement. US consumer laws may be different.
Refund then buy another copy = full rights if the new copy has a problem.
Repair of lens = no rights other than the guarantee if it still has a problem/different problem (and you'll be the one paying for postage and being without a lens as it travels back and forth to be repaired).
Both Canon and Best Buy are rich, so play it safe and let them carry the cost and risk of repairs, however slight.
