I am an online delivery novice and only using delivery slots because I live with a vulnerable person.
I have managed to book a new slot on the Tesco app but I didn't have to add any items to my basket or input card details (my card details are not saved). Somehow, I managed to copy my existing order into the new delivery slot. I clicked on confirm, the basket was full and the order just went through.
Does anyone know how I have managed to do this?!
