Update 5/21/18: It’s been a year since I originally published this Transfer Bonus series, so I've updated all three posts with transfer bonuses over the last 12 months.

Until December 31, 2015, you can up to 20,000 Starpoints with up to a 25% discount on the normal purchase price.

Starpoints are normally sold in increments of 500 points for 3.5 cents per point.

I naturally categorize miles and points into two groups:

Broadly useful
Niche programs

The first type of miles are the miles you want to stockpile if you're hoping to follow a simple mile-accumulation strategy to meet all your future travel goals. Ideally these miles benefit from cheap award charts across all classes of service and to all regions without incurring fuel surcharges on awards.

By contrast, niche programs have some great values on their award charts, but lots of flaws.
