Bought some wine at wine.com for a total of $107 I used the US Airways shopping mall which offered 1 mile/ dollar. I quickly clicked through the links and made my purchase. The next day, I saw that Delta Skymiles offered 2 miles/ dollar. I was pretty upset by then that I didn't bother to check. Today, I saw that AAdvantage eShopping was offering 4 miles/ dollar. I feel really cheated. Did I get a bad deal? On another note, is 1.5 Hawaiian miles better than 1 Delta/US Airways/American Airlines mile? I just bought a $399 iPad 2 from Apple Store and clicked the Hawaiian Airlines link to purchase it. I'm currently having second thoughts. Some guidance would be greatly appreciated.
