I have a Meijer credit card.  I have it because they offer me a $.05 per gallon discount on gasoline.  That $.05 discount makes a difference for me as to where I  buy my gas.  After all, if all of the other gas stations in the area are selling gas for the same price,  I know that I can buy gas for $.05 less at Meijer than the other stations.  So I will buy my gas at Meijer.  And since I am already at Meijer, I will quite often go into the store and buy milk or orange juice.

And, since I pay all of my bills at the same time, I pay off the Meijer card along with the Discover card.

But, I recently discovered that even though my Miejer bill is due on the 15th, paying my Meijer bill on the 10th is not good enough.  It take Meijers a full seven days to process the payment.
