The 25 bucks includes sales tax. He didn't overpay.

Actually, I missed the OP's other post where he said

"I was buying 16 rolls. with a 4 for 3 deal I should have been paying
for 12 rolls. I multiplied 12 times the sticker price(+tax), and
decided that is what I should have paid. The "percent off" was
irrelevant at that point."

Which is the same I was implying.
