Why did they discontinue it?

My girlfriend’s favorite drink is the Fruit Punch Truly, but it appears they discontinued it as single 24oz.

Is this common for a 24oz flavor alcoholic drink (fruit punch seemingly a staple flavor in a lot of consumables) to be discontinued?

Seems like they can only be found in the variety packs (which has flavors she doesn’t like and I despise trulys).

Thanks!
