Add a Food Bank Donate Button to Supermarket Orders

With Food Banks being so vitally needed at the moment and with the huge increase in online supermarket orders adding a donation field seems a good way to raise loads of money.

I used to drop a few items in the food bank baskets when shopping but as I am now not actually going to the supermarket I don’t have this option, I have donated money directly Food Banks but think the Donate button would encourage more people to do so easily.
