The possible discount available for a big collected order on a Tuesday will be better than 50%. When the NHS used to try to keep to 13 week wait the staff were bribed to work an extra couple or three theatres on a Sunday. Of course the staff are still due a lunch break, but we all have better things to do, especially the medical staff. So if we started at 0800, on the dot, and all worked through lunch we, the docs, got Dominos to deliver to the theatre for 1200. I cannot remember how many we bought but we got the works, pizzas, wedges, sauces, fizzy water, softies and usually a bit of leftovers from Sat night a bonus. They were delivered in the keep warm bags which were collected the following weekend and about half staff were vegetarian so carefully divided into two lots. There was always loads left over. We made a deal with the local manager (OK Sunday 1200 delivery so he may have just needed to get an extra member staff in half an hour early). The bill for 2 theatres was £60 and for 3 theatres about £100. A theatre team is about 8. I make no comment about number of pizzas to order, just the discount you can get. We were paying about 30% of the list price, delivered.
There are comments above about profit margin, it is truly unbelievable. The published ROCE for Dominos UK and Ireland in annual accounts is between 60-70% so the gross margin has to be more. One further comment, Dominos is not a food supplier, it is a software company. When after a few beers you pull out your phone and tap "my regular order" everything, from putting order on "production line", arranging position in delivery schedule and visiting your credit card needs no human intervention.
Happy Birthday dd, have a great time
