All I can say is that since I quit smoking we've saved £100's
I noticed today that most brands are around £7 or more a packet.

We can very easily live on £6 per day. Often the food we prepare will last 3 or 4 days.
Tonight we're cooking up Mung Beans with beansprouts, spinach, watercress, tomatoes and Pork belly slices.
Total cost for the ingredients is £6.50
Should be enough for us both for 3 days. (well as long as I don't eat too much )
It's one of my favourites.
Tomorrow, we'll make a chicken curry. That'll last us a few day as well.
Even a good old fashioned Beef Stew is really inexpensive.

If I was still smoking that alone would cost us more than spend to eat
