Aaah. Sorry, didn't catch that.
If he insists, let him put the suff away somewhere, like in a box in a closet or under the sink. Then, after a couple of months, you can drag out the now-dusty box, and say, "Do we really still need to keep these?"
That always works with my hubby
Or just make him tell you when he thinks you'll need the old ones! Or just put your foot down.

And yes, friends or charity shop sounds good to me.
