I know exactly what I want to give to DH for Christmas. It is a practical gift, but something he would not likely get for himself. I have the money set aside for it.
This afternoon, on a FB selling group, something that we have needed for ages for our DD became available. She is disabled, and we struggle to transport her wheelchair - a folding pushchair in her size and with all the options she requires has become available at less than 15% the cost of buying new, however it is still $575 USD. It is even pink 
The seller has agreed to hold it for me for 3 weeks so I can get the funds together for it, but the only way to do that is to wait until after Christmas to buy DH's gift and use that money towards the chair.
So, do you think I should give DH a card with a note of what I will buy him, and then get the item after Christmas, or am I being a Scrooge?
Fortunately, I already have gifts for the DCs.
