Was ater some tube and plates to make up my engine mounts. After trawling ebay this place seemed quite cheap and had all I was after: http://stores.ebay.co.uk/bejengineering
I emailed them asking for postage discount as I was buying 3 seperate items and postage added up quite alot. They got back to me with a postage price was was even cheaper than the quoted price of the largest item on its own! THEN a few hours after paying for it, they sent me a refund for £1.15 as it had worked out even cheaper when they came to weighing the full packaged items.
