When I started reading about the US Airways Grand Slam I set my goal at getting to the 16 hit level which would earn me 25,000 bonus miles. I was looking to do it as cheaply as possible.

Here are the hits that I went for:

1-Points.com transfer– I transferred 4 AA miles to US Air which earned 1 Dividend mile-Free/4 AAmiles
2-E-Rewards– cashed out $25 of survey money for 500 miles- Free
3-US Airways Shopping Tool Bar– 3 searches earned 2 miles- Free
4-US Air Shopping Mall– Amazon.com purchase I would’ve made anyway- earned lots of miles- Free
5-Biscoff– Cookie trial pack- earned 264 miles- $13.47
6-Thanks Again– restaurant.com purchase- 100 miles- I put my cost at $1 since I usually pay $2 for a coupon but this one cost me $3. The points were a pain to post
7-Office Max– earned 6 miles for a cheap purchase- $9.74
8-US Airways Credit Card- earned 29 miles- Free
9-US Airways Dining– earned 87 miles- Free
10-1-800-Flowers– earned 240 miles for peanut brittle – $21.75
11-Sky Mall– earned 12 miles for cheap purchase- $12.24
12-Audience Rewards– answered some quiz questions to earn 12 miles- Free
13-ShareBuilder-I transferred $50 and did one trade- earned 2500 miles-$5 (a trade costs $10 but by trading on a mobile device you get a $5 rebate)
14-Mags 4 Miles– I transferred miles for a magazine subscription for my wife- Cost -600 US Air Miles
15-Super Shuttle– booked a shuttle transfer that I did not take- earned 50 miles- $5
16-Track It Back– earned 500 miles- $24.94

So for $93 I earned 25,000 bonus Dividend Miles and for the actual purchases 3,700+ Dividend Miles.
