Those of you who care surely already know, but those who don’t might want to avoid certain retail locations once the sun goes down tonight.

Twilight, that suckalicious sparkling-vampire movie starring Robert Pattinson (eeeee!) and Kristen Stewart (Bella!), is out on DVD tomorrow. But it’s not any ol’ DVD release: It’s a two-disc Special Edition DVD, and it’s going on sale in just less than 12 hours, complete with parties at Borders, Walmart, and Blockbuster locations across the country officially starting at 10 p.m.

Certainly, though, the lines will form much, much earlier. Especially considering that the Twilight folks have not only promised plenty o’ giveaways, but “Twilight actors and filmmakers will be making surprise appearances at select locations throughout the country!”

And if those facts don’t make you faint, you’ll certain need a splash of water to the face and a cookie if you decide to give plasma at one of the blood drives select Walmarts will host. It’s unclear whether the Clinton, Md., store — apparently the only Walmart throwing a Twilight party — will be participating.
