Cheap vinyl storage options

What are some cheap storage options for vinyl? I've got ikea shelves, crates of various varieties, and some shelving I've made myself. All are now full. I need something in the $10-20 range, nothing fancy, just enough to get the job done.

hey i was just thinking about this. i only have enough storage for about half my records and the loose ones are just lined up face-forward against the wall. which isn't great.

for stuff i can't fit on my shelves, i use those white cardboard boxes with lids.. not the best thing in the world, but they're stackable and i feel more comfortable having them in a box on the floor rather than just on the floor leaning against something, waiting to be kicked over or w/e.
