I always had that same problem with my MIL, now that he is 20 she just sends him a check, thank goodness, but I understand the feelings of frustration because when he was little and wanted a specific toy and I told her which one to get and she said ok, then I didn't get it and neither did she, really hurt me when my son didn't get what he wanted. I would buy the gift card from your son and just hold on to it and give the money to him, then use the gift card when you have to buy your MIL something. Merry Christmas everyone.
