We did not so far, and we didn't growing up .. maybe there are in different cultures/backgrounds/faiths.
Our kids were like yours - just wanted money more than anything, or had something specific in mind at that age. It keeps on going like that from then on ..
I would focus more on some kind of experience maybe? Even that wasn't so important here though really. We just still try to celebrate and do a whoop dee doo but kids don't always want that (especially as they get older).
ETA: Just an idea.
We just did something fun for one of our kids' birthday where the entire day was spent doing what they wanted. Hubby took day off and so we did brunch, presents (so out of order), outing to fun place, another place (both inexpensive), home for swim, pizza, cake, game of their choice (no groans),then movie (their choice) at home ..
It turned out to be the most fun we've had in ages. It was not at all what I thought they would have chosen. Even a half day would be enough - because we were exhausted, and it wasn't that expensive. They did something low key with a couple of friends outside of this another day.
I just did a banner - bought one of those cheap dollar store Happy Birthday ones and stuck pics of kid in between spaces of letters.
We did the something you want/something you need/something to wear/something to read gifts ... and then some *fun* (inexpensive) ones from pets. So you can still do your big gift (fortnight money) - for us it was apple iTunes cards. It was just enough and not over the top.
My kid said it was their favorite birthday so far. So I'll pass that along :)
