The store is nicely laid out and illustrated. The order of what you need was accordingly simple. The payment option via direct debit via Paypal was very easy and hassle-free, especially if you, like me, have no account at all with Paypal. The delivery time of 2 working days over the weekend was fully ok. The whole thing was of course rounded off by the enclosed gummy bears. :)
It does not have to be Amazon, the dealer around the corner in Germany can do it just as well.
