SciFi Classics: 50 Movie Pack Collection. Only $10.49 on Amazon. It came out in 2004, but it's still available, and you're hard-pressed to get a better deal in these tough economic times. These movies are guaranteed to have a beginning, a middle and an end, after a fashion, but they're not guaranteed to be good. But at 20 cents a movie, who cares? It's your chance to see Brandon Lee in Laser Mission, and so many others. Your friend/partner/child will be thrilled/horrified.
The Alien Fear Collection Featuring The Absence of Light, Willows Way, 6 Angels, and Exterminator City.) Here's an actual review from Amazon.com: "I saw these moves before, and could not weight to get them my self. Great sci. Fic moves very scary and sexey. I would reckimend these moves to any one. I am glade I bought them." With a recommendation like that, how can you go wrong? But seriously, these are some great cheesetastic movies featuring people like Julie Strain, for just around $14.
Grindhouse Double Feature: Zontar, The Thing From Venus (1966) / In The Year 2889 (1967) Easy to track down for around $3.50, and it features a monster from Venus named Zontar who cuts a swathe of rampage across the 1960s swinging scene. And then there's the post-apocalyptic Year 2889, where only one houseful of people survives the end of the human race — and then an alcoholic stripper shows up. Good for those three AM munchies fueled trash culture watching sessions.

Classic Sci-Fi TV - 150 Episodes. Starring Captain Z-Ro and Rocky Jones, Space Ranger. Did I mention there are 150 TV episodes on this box set, and it goes for around $10? And it includes one episode of the show intriguingly called "Here Comes Tobor!"

This goes for around $5 and includes Dennis Hopper as a sailor on leave who falls in love with a girl who works as a "mermaid" at a circus carnival — but then it turns out the girl believes she really is descended from ancient sea creatures and must kill when the moon is full. How can that be bad? Also, a crazed surgeon accidentally decapitates his fiancee, but keeps her head alive — and the head plots revenge telepathically.
