You can get them at Staples or Office Depot or even Wallmart.

This might be close to what you want.

Walmart carries them in the craft department , where all the beads are located for 97c to 1.99. depending on what size.

Thanks everyone for your help. Hi Carol, long time no see!

Any large craft retailer will carry them.

if you have a michael's craft store near you, they have 100 in a bag for $1.49. they carry about 5 or 6 different sizes. i'm sure a.c. moore craft store would have them as well, since they basically carry the same thing. (not sure if that one is in your area either).

hope these further suggestions help you.
