I'm sure everyone's had the experience of filling their shopping trolley up with all the ingredients to make say wraps except the store is sold out of actual wraps. Like you have all the salads and fillings etc but no actual wraps.
Now I have to find another store nearby that has my missing ingredients. DURRRR RAGE!
There's a start up idea in there somewhere.
like what if I could check off my grocery list and any items not checked off, i automatically get a list of the nearest places relative to my current location where i can get that item.
