I aggree with Leasha (So much agreeing here)That is a great way to start.

I use mine for everything. This leaves my pay sitting against my home loan for as long as possible. I have a budget and I don't buy anything that is outside of that unless i've discussed it with my DH first and visa versa for him. That way we know exactly how much out credit card will be each month, and we know we can pay it off as it is all food and bills.
