Just ordered some Playmobil for my lad - been waiting for the Egyptians sets to be released (they have come out today).
Anyway, we were spending £45, with a £6 delivery fee. Instead of that, we spent another fiver, and got free delivery. The site then added a free gift to our basket too - we got the deep sea diver board game. Nice.
There does not seem to be any publicity with this freebie, just the message that you get as your basket nears the £50 total.
I know it is not terribly exciting, but a freebie is a freebie, and if you want Playmobil, the official online store is the best place to get it - much cheaper than the regular shops most of the time.
