I got a free coupon in the mail recently for a free bottle of Dr Pepper, and saw it was good for 16, 20 and 21 ounce bottles. Never seen a 21 ounce bottle before.... where are those marketed?

They have been around during football and basketball seasons. They are promoted as having 5% more and sometimes have bumps on the bottles to feel like a basketball or football.
I found a post on here from 2004 I bumped up.

I remember the football-shaped "extra point" bottles from a few years back. Haven't seen them lately though.
