Everyone likes a good reason to celebrate. Birthdays are a pretty good reason. Rebel Minis is having a birthday. As such, they are celebrating. And it should stand to reason, then, that everyone likes that.
From now until the 13th, you can get everything over on the Rebel Minis site for 20% off. Just pick out what you want and use the code "Birthday" (without the quotes) during your checkout. This sale only goes until Sunday, so better head over there now.
