Buy your next car without financing it

Pay off your credit card bills in full each month

End the escrow account on your mortgage

Pay bills in full, rather than a payment plan

Take advantage of financial crises

Not worry about the minor disaster that recently hit

And more…

Build the “buffer” and benefit!
