I am so livid over this and I know many here have there card so I figured I would post up what the company is doing. I called today because I used my card for groceries and was told Wal Mart is not a grocery store despite selling groceries. I am okay with that. I can see them doing this. I'm okay but not happy but thats life. What I am not happy is the fact that Discover WILL NOT give you more than 1/4 percent for any and all charges at Wal Mart, Sams Club, Costco or any other place they feel is a "wharehouse" type place. Yes folks even when you spend the $3,000 annual amount you will only get 1/4% if you use the card at a wharehouse type business. What the names of said businesses are unknown as nobody is able to show or tell me where these are. And if they are mentioned its in minature print.
