Canada-based Points.com has come along way since its humble beginnings back in the hayday of the internet.
Basically points.com is place where you can track, swap, share, give away, (nominally) buy, or redeem points from your airline frequent flyer and hotel frequent stay programs.
In my not so humble opinion here are the 3 best things about Points.com (in reverse order ala David Letterman)
3) Gift / Share - I am the greediest bastard on the net, but I am not above giving my mom my ff points so she can come see me (and cook for me and clena my filty house :) )
more ....
2) Buy - Points.com does nothing more than point you to the locales where you can buy points at popular program. This is a huge help if you have 23,914 points (1086 shy of free domestic ticket) ... I may have to steal some of their glory and list the links here on Moe Greenbacks.
1) Swap and Redeem - you belong to a points program where you earn frequent whatever for doing something and you don't care about doing more of the same ... for example you are a consultant and fly every week. You would be happy if you never saw a plane again, but you love to read. No problem swap your American Airlines points for Amazon gift cards and order away. Brilliant.
These guys at Points.com are really smart (for Canadians)
Happy flying,
Moe
