There are certain things that I don't like to substitute like my vegan stuff that I don't want to get something with dairy in it so I make sure those are never substituted, but with meat, cheese, snacks, and anything else usually I substitute it and we always get something better.
One time I got the small package of sliced cheese and they gave me one that was so big I swear it lasted a month

and that was us feeding some to the dogs

It was ridiculous
One time I got a smaller mouthwash and they gave me a huge one and I just finished it and it lasted 3 months

they always give you something bigger and better
