I received a $100 gasoline coupon when I test drove a car at a Chevrolet dealership in September 2008 in Winnipeg, Manitoba. I followed the instructions at FreeGasCentral.com of purchasing $100 of gasoline in each of the next 4 months at the same outlet and I mailed in my receipts monthly. Each month (October, November, December, January) I was to receive a $25 gasoline card. The last card was to be a $30 card as my $5 registration fee would be reimbursed.
