Amazon's Gold Box Deal of the Day today is a PlayStation 3 with Instant Game Collection included with a 1 year PlayStation Plus membership for $250. Basically you get a free 1 year membership to PS+ and that is your Instant Game Collection.
Its a 320GB and from the pic on Amazon's site it looks like its the older original slim model (with the Blu-Ray slot loader), so this might be the last chance to get a deal on the original slims, since Sony has quit making them. Also I don't think Sony makes the new slims with 320GB. I've only seen the new slims with 250GB and 500GB. So I'm pretty sure its the original slim model.
A 1 year PS+ membership is $50 and if you can still find that 320GB PS3 original slim it sells for $250 normally I think, so basically you're getting the PS+ membership for free.
