# Pi Day Pie for 3.14 points per dollar

13

Every year I like to celebrate Pi day (March 14, AKA 3/14, AKA 3.14) by showing a way to buy pie and earn 3.14 points per dollar along the way.  Keep in mind, this is a fun challenge, but not a recommended approach to buying pie.

### Tools needed

In order to earn 3.14 points per dollar buying pie, you need the Chase Sapphire Preferred credit card.  As in past years, weâ€™re going to take advantage of the fact that the Sapphire Preferred card gives cardholders a 7% annual dividend.  So, if you earn 2 points per dollar with your Sapphire card, that becomes 2.14 points per dollar with the annual dividend.  We just need a way to tack on one more point per dollarâ€¦

### Step 1: Go through Ultimate Rewards Mall to GiftCertificates.com

Make sure to log in with your Sapphire Preferred card so that points earned from the mall will get the 7% annual dividend.  Currently, the Ultimate Rewards Mall is offering 2 points per dollar at GiftCertificates.com.  Click through to GiftCertificates.com.

Pick a restaurant that sells pie and buy a gift card.  For example, Boston Market lists the following on their menu:

Pay with a card that earns only 1 point per dollar at GiftCertificates.com.  For example, pay with a Chase Ink card or a Chase Freedom card (but only if you do not qualify for the Freedom cardâ€™s annual 10% bonus given to checking account holders!).  You cannot pay with the Sapphire Preferred card because the point earned from this purchase will qualify for the 7% annual dividend, and that will mess up our math.

Eating the pie is optional, but expected.

Hereâ€™s how the above procedure results in 3.14 points per dollar:

• Ultimate Rewards Mall: 2 points per dollar
• Sapphire Preferred 7% Annual Dividend: .14 points per dollar
• Credit card spend: 1 point per dollar
• Total: 2 + .14 + 1 = 3.14 points per dollar
