O-Rings- Where to buy?

I want to purchase a box of O-Rings for flashlight additions and replacement.I know Shiningbeam has some , anyone else?

Just about everyone sells o-rings in the usual 10-pack. Any specific size you are having trouble locating? Standard or GITD? Rubber, silicon or neoprene?

DX, KD, CNQG, I-O all have a fair selection of o-rings at good prices.

You can by O-Ring sets from Harbor Freight if you have one nearby. They are inexpensive and have a large assortment of sizes. (http://www.harborfreight.com/catalogsearch/result?q=o+ring)

I have bought my Flashlight O-Rings from DX in the past however. There, you have a choice of Black, Orange, or GITD on some of the sizes. Some have reported that DX shipping has been very slow lately...

That's what I was looking for sort of a Multi Pack with different sizes . DX has them but they are all of the same size.
