As GrahamB and Tahra have mentioned, store displays are indeed destroyed after their use including the big figures which in my opinion is not only wasteful, but destroys history.
As the saying goes "It is not what you know, but rather who you know"
I will not be disclosing where I get these sets from as I am not willing to lose my source, nor get them in trouble for doing me the favour. PM strictly forbids the sale and or give away of any advertising material that was not intended for general consumption (i.e Items not intended to be given to the general public) This includes but is not limited to, posters, banners, display stands, display boxes, display cases, counters and giant figures.
Playmobil in Canada currently does not require toy stores to return the giant figures/ display items or to provide proof of destruction. The cardboard cut outs and stands usually just end up in recycling. Most toy stores as they are required to pay for the giant figures just buy one and usually keep it for a very long time. A common one around here is the pirate captin. Canada is not huge on Playmobil like in Germany and therefor the selling of playmobil displays is not as such a concern currently for Playmobil Canada though this may change.
Toy stores in Canada also do not get sent a printed order list for display items anymore. They are either required to go online or a PM sales representative comes to the store and brings along a trade advertisement catalog. I would love to get my hands on one of these but that is currently not possible.
I will be getting other things as well such as the following stand:
but only after they are finished with it. Reason being is that the toys that stock it come with it. The store has to purchase 4 of set 9219, 6 of set 9220 and 8 of the following sets: 9221-9224. These purchases must be made prior to the beginning of the new sale year (at least 4 months prior to toys hitting the shelves)
I will not be a great source for PM information as Canada is one of the last countries to get the sets with most toys sold here coming out the year prior in Germany.
