Our mutant overlords at Joystiq are reporting that the Micro Center $100 rebate deal we reported earlier this month has been extended to December 31st. For those who don't recall, the deal applies to both Core and Premium 360 bundles. We suspect the deal is legit, though the official rebate page has not yet been updated with the new dates. So, if you're still on the fence about the 360 (or looking for a good gift idea), you've got some more time to think it over. Remember though, there are only 19 Micro Center locations in the US, so you might want to see what the real price is after you factor in gas and tolls.
