Serious bike shops appear to have them (not anything against REI, it's just that they're not exclusively a bike shop). My bike shop has inserts in a big jar on their parts counter. Here's a site I found that has them, though you have to buy the whole strap assembly along with the inserts:

BTW, the Ortlieb USA people seem a little questionable....
