When I tried to google the latest American Express deals, it led me to the link below offering $100 Reward Dollars to sign up.
When I logged into my existing american express account using google search: American Express Blue Cash Login, they offered $150 to sign up. See Below
What stores are considered Grocery Stores by American Express that will enjoy a 6% cash back?
Supermarkets are firms which primarily sell groceries such as:
Shoprite, Pathmark, Superfresh, A&P, Kroger, Safeway, SuperValu, Publix, A&P, Albertsons, Whole Foods, etc.
Costco, Target and Walmart are considered "big box stores" and therefore, 6% reward for grocery stores does NOT apply.
There is a $6,000 limit on purchases that qualify for 6% rewards. So the maximum cash back in rewards calculates to be $360 per year. The annual fee is $75, but it should be offset by a welcome bonus of $150 which you should receive after spending $1,000 in the first 3 months
