I would have no problem in paying more now than I did years ago, for the same size box of Kleenex. What annoys me the most is that the number of tissues has been downsized so much that it seems I'm always running out and have to go get a new box from the cupboard. I try to buy the brand with the most in the box, but always watching the price per sheet. It seems to me that it should cost less per unit to put more product in the box (i.e., don't downsize). Just look at the bulk product section of your supermarket.

By the way, the same thing applies to toilet tissue. The old single roll of 400 sheets has been incrementally downsized to a roll of 200 with a much larger core. Now it's been reintroduced as a double roll with the smaller core again.
