Most credit cards have programs where if you click through a particular portal, you get additional. Here are some I use:
- Mileage Plus Shopping. It doesn't even matter if you use someone elses credit card. If you click through this portal to say Newegg, J&R or Blue Nile, you get a boat load of points. Best deals at 3 points per $1 on Blue Nile for instance.
- Bank of America Signature Rewards Shopping Mall. Some good ones are 120 points if you buy on Alaskair.com in addition to the points you'd get anyway. 3 points/$1 on American Eagle Outfitters, Beach Camera, iTunes.com, J&R, Mac Connection ; 2 points on Apple.com, Avis.com, 1500 points per subscription on Audible.com, Best Buy, Marriott, Sheraton, ; 4 points on cooking.com, Starbuckstore.com, the golf warehouse, Tigerdirect; 6 points on drugstore.com; 9 points on ebags.com; 1 point on Enterprise, Newegg; 15 points on Skype;
