Did you ever buy or plan of buying a Lego Set for your kid or maybe for yourself? If you've bought, what's the cost if it?

Yes.. many lately..
My eldest is super into it and I can’t resist.
Since i like to stack sats, i try not to spend much. So i often go for second hand sets.
We are not collectors because we open and play with them, so, new sets are like 1 or 2 a year tops.. the rest is second hand.
We have more than 100 figures now.. its getting out of hand..
