I am insulted by her gift suggestion

DEAR MISS MANNERS: I found out that when my mother-in-law asks for gifts, she asks for things that she would not buy for herself.

This came up because she recently mentioned that she never orders from a specific brand because it is so overpriced. She had asked for, and I gave her, something from that brand last Christmas.

I am insulted that she feels it suitable for others to spend their money on things that she thinks are not a good value, especially since that gift has gone unused since last Christmas.

I realize Miss Manners does not like gift registries of any sort, but since they are a common reality, what is the proper etiquette for what goes on them? I personally never list anything that I would not buy for myself, whether it be the cheapest asparagus tongs or the finest silk scarf.
