Isn't this how stores used to be run anyways? Give the list to the grocer, he get's your food ready, etc?
I don't understand why Canadian and US prices are so sticky. In Europe, a frozen pepperoni pizza might cost you 3,78 EUR and the vegetarian will cost you 12 centimes less because the retailer passes on their differing costs.
Meanwhile in Canada/USA, I'll take the 3-meat because it's the same price.

Be careful, even though they're the same "price", the net weights are different so they're not actually the same price.
