Where is the best place to get the bolts? Are vag bolts on eBay well priced?

For faster delivery and original quality I'd go straight to your local dealership's parts department, usually there similarly priced to eBay but you're guaranteed quality. In Ireland parts collection usually takes 2 working days (parts are shipped from the UK), so I'd expect it's next day or same day collection in the UK.
You can also go to Skoda dealerships, they sometimes sell the parts cheaper (or so I hear).
Best to call the parts departments of each just to get quote for prices, double check with them that they are quoting with VAT included, ask for estimated collection time, and then compare with eBay.
