Diamante Buckle HELP!!!!!!! with pic

Ok so our invitations came in (YAY!!) now here it goes. I am looking for 150 diamante buckles (silver) that will fit a 22mm ribbon. Please help. I found a package at walmart (surprisingly enough!) Only problem is each package has 3 different types of bucles so i am going to be paying for 450 buckes and only using 150. Any one have any ideas? No craft stores had them
