Below are my sponsored recommendations:For fast food and restaurants
it is possible to get 2% with the Citi ForwardFor groceries
I would normally recommend the American Express Blue Cash
for its 5% but that does not apply to warehouse or super stores like Walmart or Sam's Club. It is worth checking out nonetheless for its 5% on gas, groceries, drugstores.For regular purchases
the Discover Escape
gives an unlimited 2% in rewards.For sign up bonues
which you mentioned, check out this page for travel rewards credit cards
. There are several, some offering incentives worth up to $300 for the start of 2011. The best offers do charge an annual fee after the first year.For balances
I generally recommend keeping using a second card for simplicity. The Discover More is currently running two great offers for balance transfers and purchases
My other recommendations:For cars
the GM card was relaunched for 2011 and has 5% but there is a redemption cap which varies by vehicle. This is applicable to new vehicles only. It is a great credit card deal if you buy new.
Congratulations and good luck with your daughter's wedding!
