I got hooked on the AARP 5% card, and just found a similar one from Citibank for the next 6 months (see:
https://creditcards.citi.com/credit-cards/citi-thankyou-preferred-card/ ).
My back up cards are:
-Amex HHonors (for the bonus, and good points on hilton, telecom, drug store, groceries - though my grocer doesn't take it)
-Fidelity Visa 1.5% (first 15K); 2% after - - will be primary once the 5% citi goes away.
-Sony Card (old one) for no forex fees (its Cap One)
-Citi Bronze AA card (no annual fee, 1 point per mile, I have my ez-pass billed to it to ensure my AA miles don't expire).
-Old Navy Visa card (my wife likes the coupons).
To be cancelled/consolidated:
-BOA 123 card (was schwab 2% card, my old primary card until they took it away and had to find a replacement [AARP for 6 months, now citi])
-Fidelity 1.5% card (replaced by the 1.5%/2.0% card above).
To be gotten at some point (had a lot of applications recently):
- Marriott card for the bonus and company travel.
- some of these other cards with points you can transfer for hotel/air miles.
I want to build up some hotel points for free travel in a couple years when my kids are bigger. I plan to use the Citi points for amazon certificates since I do a lot of x-mas shopping online.
