If I suggest a Christmas present for Mr. Spouse to my mother and she says "oh, can't you just get it and I'll pay you back?", does that constitute her giving him a present?
Somehow, I don't think so. Since I probably have more money than her, but less time, if I'm going to think of it, and organise ordering it I may as well just pay. I already have several things for him, and we are trying not to go all out this year (one big present each plus a few little things).
Incidentally we went to a craft fair on Saturday and I was buying something for a friend when I turned round and spotted him putting a bag in his pocket surreptitiously. It was very sweet. He was a bit annoyed, though, as I know which stall it was from so have an idea of what it was. But I don't mind. I didn't see it, and I get to be reminded of how sweet he is twice.
