Did a quick Google for b&m cyo premium and came up at very good price on bikester. I've never heard of them. Are they any good?
Assuming it's the same, I've used bikester.nl and also their sister site campz.nl. Seems to work. Tho recently I had an order placed, claimed as being in stock with next day delivery, only if turns out it was in Germany, came via DHL, not postnl, and took a week, not the promised order before 1500 for next day delivery...
This does assume they are the same site.
