people on here know that I am not advertising or anything like that-

I needed to get some cartridge rolls as I have a few sets of heads stacking up that need porting and Wholesale Tools on the internet has a decent selection with really low prices. You can save a lot when you're looking for just a dozen or so of each size of roll (as I was) instead of having to buy a bag of 100 from other suppliers in order to get the same price per roll. I didn't shop on their site for anything but that but for cartridge rolls it seems like a good deal. They're American made rolls for those that that matters to (I own a few chinese tools but try to buy USA if I can afford the difference).

Are you talking about Wholesale Tool Company?

If so, they're located: http://www.wttool.com/

They sell those rolls HERE for $0.43- $0.45/ea.

Some more cheap rolls HERE.

I don't know where Waters gets their abrasives from- probably China- nor do I care. Also don't know about the S&H for either place

This is one of the places Ebay can help. If you know what you need, have the patience and enough lead time to wait for some to show up, it can really pay off. My last purchase was three 100 count boxes of 3/8 x 1 1/2" tapered 60 grit for $18.30 total shipped. About $.06 a roll. Score!!

Most troublesome for me to find is anybody selling 36-40 grit. I find this grit to be the best on aluminum. Have yet to find these cheap. Even the 60 grit isn't common, most common is 120-180-240 which I find too fine for porting use.
