My DiL has always been a great help in letting me know what would be appropriate for my DCD - has often sent me a link so that I can see the product for myself. Now that they are grown up, and spreading their wings, it's not so easy and I make a donation to their bank accounts, and supply a small 'stocking filler' to open on the day. One year, DiL gave me a link to a tee shirt that DGS wanted. It was out of stock, so he eventually got his Christmas present for his birthday - in the summer.
