In case you didn't catch it, there's a Shift Code for Borderlands 2 in honor of Valentine's Day.
W3KJ3-69JR5-9CXT3-JTJJT-WSCK5

Go to Extras > Shift Code > Sign up if you have to > enter code.
You can share it, it's multiple use. Gives you some skins, and a really nice shotgun for the first character you load after you enter the code.
But the code expires Sunday, so hurry!
