Yesterday, a friend forwarded me a Google Offer for roundtrip tickets.  Within minutes, I had bought the offer and purchased my roundtrip ticket.  Victory! I saved $55 and earned a standard 2% cashback with my Fidelity AMEX.

Soon after, as a proud cashback nazi, I realized the rookie mistakes I had just made:

• Forgot about 7.5% cashback on my Google Offers purchase by going through a referral link on Ebates.com
• Lost another 3% cashback on my airline ticket purchase, because Citi Dividend has a promotional 5% back on Airlines & Car Rentals.

Funnily enough, I had just read about a new product that helps prevent mistake #2: the Wallaby Card:

Backed by MuckerLab, an accelerator in Santa Monica, CA, the Wallaby Card automatically routes charges to the credit card in your arsenal with the highest rewards.  For example, if you’re paying for dinner, it will automatically use your card that earns double miles on restaurants.  Coming from someone who carries 2-6 personal credit cards, depending on the rewards available, this is an incredibly smart idea.

Beyond the simplicity of a single physical credit card, the mobile app is a genius addition, allowing you to change how your charges are allocated, see how many points/miles/dollars you’ve earned, and browse local deals.

They’re working on supporting store private label cards, like the Starbucks Card, and there is an annual fee of $50, but the first 6 months are free.  $50 seems a bit steep, but there are so many instances where I use the wrong card and those mistakes add up.  (Yesterday’s mistake was $9.)

Perhaps the best benefit of all? You don’t need to carry around a giant anymore.
