Actually this is a good article to point out, but if one notices, this is a little dated as it was written in June when prices were still skyrocketing.This explains why the WAWA for example where I fill up makes the price per gallon 5 cents cheaper if paid by cash to offset these added fees.Back when prices were over $4 a gallon, WAWA would charge 3.99 for credit card, and 3.94 for cash. As of yesterday, the price was 2.83/gal there and there are even cheaper stations on the Jersey side of the border down around 2.71. I sometimes go that way if I am doing errands, the doctor or whoever on that side.Another concern is that since the housing market collapsed, and the lending institutions are being bailed out, there will be a greater fear of loans of any type. It will boil down to cold hard cash again. In my younger days, that's how I always paid for everything anyway, then I knew what I could afford. But then as I got older I must confess I got onto the credit card kick because I always made enough money to pay it off in one payment anyway and carrying around too much cash was inconvenient.This will be interesting to see what will ultimately happen. Definitely stay tuned.
