moneysavingtip#1: Spend your money in meth -> no hunger = no need to buy food
moneysavingtip#2: If you however need to buy some food, always pick the stuff marked with a red pricetag. The parasta ennen-dates are usually a week earlier than what they actually should be. (except for minced meat and milk maybe). Also if you find something in your refrigerator with an expired date, look at it. If it doesn't look as if it's gone bad, smell it. If it doesn't smell bad, taste it. If it doesn't taste strange, eat it
moneysavingtip#3: Visit your parents and grandparents often. A free meal is always a free meal
(and if you're lucky, you might score a few "on kai sulla rahaa ruokaan" €:s too)
moneysavingtip#4: Cancel all your magazine & newspaper subscriptions. Everything is on the internet anyway :>
moneyusingtip#1: don't be afraid to buy expensive stuff if you need it or feel that having it makes your life happier or easier. The amount of money does (for some very weird and unknown reason) have much to do with what you can buy.
And yeah.. good luck! n__n
