The TJ Maxx by me had the Ruff-Wear Knot-A-Collar collars for cheap so I bought them out. I'll sell them to you guys for $6.50, plus $1 shipping.
Here's the link to their website so you can see them:

They're remarkably reflective!
I have 9 of them:

1 large purple
2 small blue
2 large blue
2 small purple
1 large purple
All are brand new, with tags. If you're interested, let me know!
