There’s little I like more than, well, pretty much everything at ThinkGeek, but it particularly tickles my geeky little heart that one of their Black Friday specials is Buy 1, Get 1 on their plush microbes.
And yes, it works on as many as you want to buy. (That’s good, because I pretty much want to buy all of them.)
They also have those giant Air Swimmers for just $30, which is the cheapest I’ve seen them anywhere. But those kind of freak me out. Just sayin’.
