Do you know about Facebook Watch, their streaming service with real original TV shows? Their switch from 'just' a social network was years and years ago
Shopping on the other hand, is a private and individualistic activity.
I feel this is far removed from their core mission.
Some people go to malls as a social activity. Others like to read product reviews by people (sometimes well known bloggers), or watch youtube videos. Sometimes people even ask their friends for product recommendations. Shopping is to some a very social thing.
Not for me. Especially if I'm buying something fun/non-boring.
