I recently started shopping at Winn Dixie as per my friend's advice, since they offer fuel perks now. Every regular weekly shopping trip I have earned at least $1 off per gallon.
That fuel perk is good for up to twenty gallons, so that is $20 I save per fill up since that is almost what my tank holds....sometimes I get better fuel perks.
Plus I have been saving money on groceries shopping there.
It's a win win for me, glad my friend mentioned it to me.
