White Spot has a holiday promotion up for gift cards where if you spend $50 on gift cards you will receive $10 in bonus certificates.

The bonus certificates work like gift cards basically, but are only valid during a certain time period. The bonus White Spot Gift Certificates are valid from January 2nd to March 31st, 2014.

This would be better without the time restriction, but if you visit White Spot fairly often the 3 month window should be plenty of time to use the $10.

This promotion is valid while quantities last.
