A note about grocery miles - you can earn 125 miles for every $250 you spend at Safeway (or Von's and other Safeway brands) but they seem to take longer to post than most other options. It's a good way to keep an account open, however, once everything's set up. Everybody spends at least $250 on groceries over 3 years...
