Just checked my receipt and did indeed earn 1000 fuel points as well. Sounds like a mistake. That's happened in the past though when they had the deal for money off when purchasing Amex GCs. Makes this deal even sweeter. Too bad the only station around me where I can do a full $1 off is not close at all. I cap out at 20 cents/gallon at the Chevrons

Plus with only one card purchased per club card, can't really rack up fuel points on one card.
Really interesting that their block on earning fuel points seems to be strictly limited to the straight up VGC and MCGCs and everything else will likely fall thru the cracks.... (though I don't remember earning fuel points when they had the PP card deal a while back)
Edit:
Checked an old receipt for the PP cards, no fuel points. So it seems to be hit or miss on which products are blocked and which aren't.
