Ahh my silly little friend, your view of how joyus this awesome functionality will work is laughably far from the truth. This is what will happen.
"Hey fridge, am I running out of milk"
"Hello, people who bought milk also bought <insert random unrelated crap here>"
*fridge see's you've just bought some new milk*
"Hello, may we suggest the following products... Milk"
