I have DT's. Asked by family member what they would like for Christmas. One would love something that costs £10, the other would love something that costs £16 so I let them know those things.
The family member 'allocates' £25 per person. It's not a problem that I have mentioned things under £25 but I've been told it's not fair on the one that would like the £10 toy because they should have things that cost the same.
I can't see the issue here. They would each really enjoy the things so what does the £'s matter, surely it's about the actual toy and the enjoyment rather than the cost.
