I filled up this afternoon at Meijer. The god damn display on the pump was broken, so I didn't know exactly how much I had filled. I had to estimate, and I was a little short of where I wanted to be (7.5 gallons).
Price of E85: $3.29 Gallons: 7.307
Price of regular: $3.79 Gallons: 6.650
Gallons left from tank #18 (@42.81% ethanol): 2.243
Ethanol content of tank #19 (@ E74): 43.40%
I got 23.5 mpg at 28 mph average speed on tank #18.
