I'm after these two screws, however on the Dye website, postage is £11 to post 2 tiny screws, which seems ridiculous, even if it is being sent from Germany! Is there anyone from dye in the UK that I can buy these bits from?
Any of the stores in the UK that sell DYE products can get you these parts.
Alternatively, try emailing the tech team in Germany directly - email@example.com - as the website shipping rates are based on a minimum sized package with UPS. Screws etc can be mailed and would be cheaper than that.
