I don't often buy stuff, but if I do I'll mention it to the wife. She just says, "If you think it's good, get it".
She has 11 dolls houses around the house (and 2 in the loft), about 10 big boxes of quilting fabric, 20 cacti and various other house plants and the whole garden is hers to do with as she wishes. My corner of the front room is tiny by comparison.
