Bike Packing Foam Noodle?

[nelsoc]

Hey Folks. I'm going to be packing up three bikes for transporting internationally in the next few weeks. I'm wondering about the best place to get foam noodle to wrap around various parts of the frame for protection?

I've tried the local bike shop, but most bikes now come with cardboard tubing rather than foam. They helped me out with the boxes and I've got the zip ties, but foam protection is what I need.

I did check to see what was available from Amazon, but it is amazingly expensive given I used to get it for free.

Any help, insights or guidance will be much appreciated.
