Do you use convenience store apps often? (ft. Beer Party)

Lately, Japanese beers (Asahi, Sapporo, etc.) have felt much weaker to me, so I haven't been buying them much.
It suddenly reminded me of how much I used to drink Miller, but when I stopped by the convenience store to look for it, they didn't have any.
So I looked it up online and heard that you can check the stock of individual stores through convenience store apps, so I gave it a try.
A 6-can bundle of Miller was only 11,000 won, so I bought 3 bundles from one store haha.
I'm going to drink this all through the holidays!
Just a heads-up, sometimes you go there only to find out they are actually out of stock (it happened to me twice ㅠ).
If you pay in advance through the app and select a pickup time, if there is no stock, the convenience store will process a cancellation, so please keep that in mind.
