I love online shopping as the supermarket just takes too long and I end up buying way too much.
I shop with www.naturallyorganic.co.nz - they have a cheaper delivery fee and much better service.
I found the best way to do it is to create a menu plan, then create a shopping list from that and I have saved soo much money doing it that way that I can buy organic food.
If you use foodtown or woolworths, you can save your shopping lists and have a quick go through and then you are spending less than 10 mins shopping - fantastic!! I also love their previous purchase ones, for the viewing of something that you might not have remembered!
