This one is based around earning thankyou points. Would like to know what others are doing to max out thankyou points.

Here's what I do:

Restaurants:

Citi MtvU. 5 points per dollar.

Travel:

Citi PPE: 1 point per dollar + 1 point per mile flown = 2 points per dollar. Works for buying other flyer tickets.

Gas & Groceries:

Citi Driver's Edge: 6 points per dollar (for first year) + 1 point per mile driven = 12 points per dollar.

Movies & Books:

Citi MtvU. 5 points per dollar.

Everything Else:

Citi PPE: 1 point per dollar + 1 point per mile flown = 2 points per dollar.
