MPG not showing?
 

I have noticed that the MPG for my last 2 fuel-up's hasn't been calculated by the site. Therefore, it isn't updating average mpg etc. Is there a problem with the site?

Sorted it. Was because I had a partial refill

Glad you found it. Yeah, here in the FAQ are the reasons you might not get a calculated MPG on a single fuel-up: Why doesn't my fuel-up have a calculated MPG (L/100km)?

A major grocery store chain has a gas discounting program called fuelperks!. When entering the price, should I enter the pump price or should I list the discounted price?

Discounted, since that's what you're actually paying
