I'm in bulgaria (brit expat) where there is always a considerable markup cause there are no big distributors here, thomman germany is about the closest real music shop, everyone locally orders from them and charges you the delivery.
Ordered several times from Muziker, they always proved to be reliable and cheaper than thomman. I had a discussion with their customer service re a arturia keylab 88 b-stock, they informed me B-stock is either something returned within the statutory 14 days allowance (not a defect return) or if it is marked as unboxed it has been a demo unit in their physical store in slovakia, something to be aware of - the unit was perfect an worked just fine.
We still have cash on delivery via couriers and they not only interface well with this system (82p uk for the COD service) they included as part of the free delivery the cash on delivery with inspection service which allows you t oopen the box and check for defects before paying, if you find a defect you can reject it. Also very comprehensive internal order status reports and you always get a tracking number before it leaves the warehouse. Waiting for my model 15 to arrive which was 50 quid cheaper than anything locally.
