Daddy's Whack when they Don't Stack

I love my husband dearly, but he has this crazy issue with cans not stacking!!!

We go to the grocery store our favorite is H-E-B (however I think we are at Kroger in this picture) to get canned foods. Most people have a certain brand they like how it taste... not my husband, he has to buy the canned food brands that stack .... or in other words nest inside the rim.

He is VERY frugal with his money, but he has been known to spend up to 20¢ more per can just to have the ones that stack!

It's pretty funny to me so I often tease him. I guess the joke was on me, when I reorganized the pantry and the cans I bought that didn't stack, kept falling and wouldn't line up like the others.

Do you an opinion on stacking and non-stacking cans?
