Shopping Portals Earn More Rewards

Just click the link

To earn an average of 1-10 additional points per dollar spent, just search for the store (almost all online retailers except Amazon are listed) and click the link in the shopping portal. The store retail experience is the exact same post-click. You then just check out like normal and a few weeks later the bonus miles post to your account! Magic.
Here's a list of all the online shopping portals. Free to join, just need a loyalty/frequent flyer account number.

Bonus tip: They often have promotions around the holidays, so if you spend a certain amount within a certain time period you'll be rewarded with up to 5,000 additional miles in some cases.

Check EvReward.com

If you are not loyal to a particular airline or frequently fly with multiple, check evreward.com (short for every reward) which lists the earn rates of retailers in all shopping portals (including ebates if you'd rather cash back). For example, Drugstore.com has a higher earn rate of 4 points per dollar on Ultimate Rewards portal. Remember, banks, airlines, hotels and even trains have shopping portals. Don't buy another thing online without checking these portals!
