I'm surprised people are saying .25 isn't much of a difference. It makes a huge difference for me.

Quarter diopter is no biggie. Use them.

Use them up. Both my eyes used to be -4.5 and my left eye just changed to -4.75. I continued using up the stock of -4.5s and then placed an order for the new lenses.
I wish they were the same still, it's so much easier having the same px across eyes.

What would a noticeable difference be?

I'd ask your eye dr

Are you sure Costco won't take them back?

I'd use them up. The difference isn't that much. Maybe use them on days when he's not driving if it makes any difference during that time.

The one doc does. However I buy at at Costco now and it's much cheaper.

Did you read the BOLD where it's written they are NOT expired. Answer the question asked.

Also, if your insurance covers it then it doesn't matter if you have leftovers. Ditch them. He will be much more comfortable wearing the correct prescription.

I bought disposable contact lenses for my teen a while back. He does have glasses too for when needed.
Anyway, I have built up a stash as his prescription changed.
Can he use the old NOT expired ones? He is script is 2.75 and the old ones are 2.5.
Would it make a big difference? Should I just use new ones? They are covered by our plan but I am wondering if this is an issue. I don't want to be wasteful.
