Can a German child buy non-essential expensive things, like a concert ticket, console, Warhammer or whatever? (Or a video game, back when those were sold in shops.)
I bought these things while a child in the UK. I'm sure Games Workshop would have offered a refund on something unopened if my parents had demanded it, but I'm fairly sure the ticket agency would not.
The generally agreed limit (also established in court cases) is the amount of pocket money a child of the given age typically gets per month. For a 10 year old, that's about 20 EUR, for a 16 year old about 50 EUR. A console would definitely be too expensive, as would be big name concert tickets. Unless it's a recent AAA title, video games would be OK. No idea what Warhammer costs these days.
Most retailers are probably willing to take the risk of maybe having to do a refund, unless it's something really expensive (or perishable/consumable).
