You can see the price of a product in other stores by clicking on it's image and viewing the price table in the pop up product page that appears. You cannot order from 3 stores at the same time. If you did 3 seperate shops with each stores you would pay 3 delivery charges. The most stores you can order from for one shop is 2, and only if our system offers you a split cart at checkout.
If I am looking to shop at Tesco and say I select a tin of beans why can't what other stores are charging without have to go to each to check their prices.
If i select goods from 3 stores do I pay 3 delivery charges.
