Recently I have been buying my own mounts from Paper Spectrum, who do Pinnacle mounts in packs of 10 at the standard competitions size of 400x500mm, with or without aperture. They supply the most popular colours and also packs of grey board for backing the mounts.
If you want to buy your own sheets and cut them to size yourself, Wessex Pictures in Chadderton sell their own range of boards in addition to the more expensive Daler mounts. They also supply pH neutral tapes. They are a wholesaler and they come in packs of 10 or 25 sheets so members may need to share an order. Remember to add VAT if you ring up for prices.
