Heard about the new customer program that BoA is gradually introducing. Depending on the combined balances, there are three rewards tiers: Gold($20k), Platinum($50k) and Platinum Honors($100k).
The highest level offers a sweet 75% rewards bonus on cash back. This would make their cash back categories 5.25% gas, 3.5% groceries, and 1.75% everything else
(up to $1500/3months). Seems like a no-brainer.

The program is not yet available in all states, and link might be forwarded to current Platinum Privileges site. Clearing browser cookies, re-clicking the link, and selecting state:NV should get to the correct place.
