In the world of Instamart / Blinkit / Zepto, what are the things you'd step out to buy something ?

Always vegetables and fruits. You can choose quality and decide which one you can pick. What i heard from zepto DBA, who is closely working with C-team, in these apps, mostly sexual wellness products are in high demand.
Now for Dec-31, they are stocking these products!!

Milk, groceries
