@ohms: when you tell me your order number I can have a look. Most orders for PRO have been shipped, XT is a little bit behind and LT has not shipped so far because of the aquasuite which is not ready yet and a LT can not be used without it.

@nej: Deutsche Post AG (or call it Germany Post) is only responsible for envelopes and does not ship any parcels. DHL is a part of Deutsche Post AG and handles all the parcels. Within Germany you will not see much difference between both companies because you can do both things in the same post office but of course behind the scenes they go different ways
Our parcels normally arrive the next day inside Germany, within 2-3 days in Europe and within 7-10 days outside Europe. I have also seen several shippings which take more than 14 days. A lot of time passes by because of customs or other things. Altogether it is pretty normal that your parcel has not arrived so far. I would have been VEEERY surprised when it arrives within 3 days.
