You can pick which couriers you use -- I use GLS for my regular Zoolpus deliveries (every two months or so) and have had excellent service from them but can imagine it might depend on the driver -- the same guy always does my deliveries and I know him by now! They will usually leave a delivery with a neighbour if you aren't in.
Zooplus are generally excellent as well, highly professional and some of the best customer service I have had from an online company in replacing a missing part etc. However the packaging IS terrible -- I have complained before at how flimsy it is. Delivery times also vary widely -- remember it is coming from Germany so I rarely get mine in 5 working days -- usually within 7 though. They should refund or replace broken items -- there is a procedure to follow on the website. I have waited two weeks for items from the UK and usually get Zooplus deliveries faster than UK deliveries!
