Trailing around a large shop with a little one and a two year old never seems like the most fun activity, and it takes such a long time to get round these gargantuan food meccas that by the time you've finished you feel like collapsing into a dark room for a couple of hours.
Online grocery shopping is nothing new, but what is new to us is a site that helps us to compare the cost of the food in our shopping trolley with all of the major stores: Tesco, Sainsbury's, Asda and Waitrose.
Various supermarket TV ads will have you believe the food in their 'average household basket' is the cheapest around. However, look closely at the basket and you might well see things that you would never dream of buying yourself (I never like the taste of cat food, for instance).
This site (mysupermarket.com) lets you do your regular online shop from your regular supermarket, and tots up how much the equivalent basket would be in the other stores.
Then, you just pick your store and place your order.
Very simple, and easy to use.
For our last two online shops, Waitrose (yes, Waitrose!) have come back the cheapest, further bolstered by their policy free delivery for orders over £50.
Each time, the comparison has saved us at least £10.
What's more, you can receive a small sum from Topcashback.co.uk on every online shop.
