Given the usually high cost of these I buy velcro sanding discs and cut them to size/shape,This has the added bonus of sharpening my snips.Boxes of 25 or more can be bought at any refinishing services or motor factor's(see yellow)for less than £20,economical.However,www.axminster.co.uk,supply them under the name of delta sanding sheet's.Online,or an exelent catalogue for drooling at.
