I understand that, but when I did the math, I realized that the extra percentage point on gas, groceries, restaraunts and Disney purchases would more than pay for the $48 annual fee. The extra points on gas purchases alone make it worth it. We normally pay around $65, give or take, for a tank of gas in our vans. At least 4 fillups a month times two vans comes up to about $520 a month on gas (YIKES!!). $520 a month multiplied by 12 months comes up to $6,240. One percent of that would be $62.40 a year on gas. When you get the premier card and get 2% on gas purchases, that's an extra $62.40 a year on gas, to offset the $48 annual fee for having the card. So that's a net extra $14 or so of Rewards points on your gas purchases and now you're all set to get double rewards on groceries, restaraunts and Disney purchases. If you go to WDW every year like we do, then think of however much your annual WDW trip costs and double the rewards points for that.
I work at Walmart SuperCenter and I initially had a question of whether Walmarts are coded as grocery stores for the double rewards points, since we do about 95% or more of our grocery shopping at Walmart. I never got a good answer from anyone on this, but my monthly bill says it all. Under "grocery 2% points", I always have a decent number of double points and since the vast majority of our grocery purchases are at Walmart, I can conclude that Walmart (at least the one I work at) counts as a grocery store for the purposes of this card. Now whether that is ANYTHING purchased there (such as TVs, Chainsaws, etc) or grocery items only, I don't know.
But long story short, I find it far worth the $48 annual fee for all the double rewards I get.
