don't you love how the power companies can change a "contract" with out a mutual agreement but if i said to my electricity supplier "i am changing the contract" i am sure they will accept it. NOT
if you can afford a small credit purchase for something that you want and you can afford to save up for the item at the same rate (I.E. $70 a week) then I say it would be great. but if you are at a point where 70% of you income is paying off credit then forget about it.
I can't save for shit but i can pay one thing off at a time on credit with out a problem. many years ago i had many things on credit and it nearly bankrupted me but now i get 1 thing only at a time on credit and have no problems paying it off
