looking for some sandpaper to start practicing restoring on some crap blades I picked up super cheap.

Only one problem. None of the hard ware stores in my area carry the variety of grits I need. Most only go to 150.

Any suggestions guys ? A dude at one store suggest I contact a cabinet shop (which there are no shortage of in this area of high construction), and try to get it through them.

Anyone order from a particular vendor ?
