It's pretty much immaterial whether "origin" or "destination" vat applies: rates on bike parts are pretty much the same in major eu jurisdictions (there are no duties or taxes on bikes or bike parts in intra-EU trade apart from VAT). The important thing is that it's the seller's responsibility to settle the VAT: the price you see on the website (inc shipping, obviously) is the price you pay. You don't get hit for anything more once you've paid the supplier. I have often bought stuff from german websites (eg bike24 and rose versand): they tend to have a better range than uk sites and better prices, and the shipping is little more expensive and very little slower. And a special word for laufrad.net if you want wheels, especially dynamo wheels.
