Community DVD Sales
I forgot to mention this yesterday, but in case you don't have them or want a gift for someone else, the Community DVD sets were on sale for Black Friday at a couple of places and at least two still have them at a discount. The prices aren't as low as last year, but they're still good deals. (Note: I don't know if deals are only available in the US, but it's probable.)
Amazon has S5 for $10.99; the other seasons are also on sale at around the same price or $7.99 (S5 is temporarily out of stock, but they'll ship it as soon as it becomes available again)
Best Buy has S5 for $11.99; the other seasons are also on sale at around the same price or $7.99 (I bought a copy of S5 there yesterday)
