Expected behaviour when adding items to your ‘favourites’ [duplicate]
This question already has an answer here:
I am tweaking our current user journey for adding specific items to your 'favourites' list.
The question is: if the user isn't logged in when they add an item to their 'favourites' - should they be prompted to log in at that point?
Or should they be allowed to add more items until they click checkout and then be prompted to log in then?
I feel it would be less disruptive to what the user expects if they need to log in after clicking 'Checkout' then being prompted. But then my concern is if the users don't click checkout and the session ends. They could potentially lose their items.
