What sells on a live stream for grocery?
Things with a decision in them. An item somebody is uncertain about — fit, size, quality, how it behaves — sells on a stream, because the stream answers the uncertainty in real time.
What sells, and what does not
What does not sell is the commodity line the buyer can price-compare in ten seconds. Putting it on a stream turns an hour of attention into a comparison shopping session.
Live selling works where the product has to be seen moving, worn or demonstrated, and does little where it does not. For a grocery or food store in the UAE, the answer turns on one thing in particular: Grocery margins are thin and baskets are large, so the whole model lives or dies on delivery cost per order.
What is different about the UAE
Delivery expectations in the UAE are set by same-day services, so five-day shipping reads as slow whatever the price.
Card payment is the norm in the UAE, with cash on delivery still expected by a meaningful minority.
What is different about a grocery or food store
The work is not the video. It is buying inside the video, because a link to a product page loses most of the audience.
Where a mobile app comes into it
Weekly reordering is the behaviour, and an app that remembers the last basket removes most of the work.
