Please help.

Keep in mind, I have very little packing supplies at home, so lets just assume I have to buy everything.

I'm told/read that it should be around 100-150 to ship 4 wheels via UPS...if I go to a distribution center directly. Going to a UPS store I hear it can cost $250.

Any advice on what packing supplies I can get for cheap? I'm planning on shipping the wheels/tires without air, and in 4 separate boxes.
