From the StylinOnline guy himself:
I am running a holiday special good only until Monday. This special is going for all my merchandise but I thought you folks would like to take the opportunity to receive 10% off some of my restocked Firefly or Serenity stuff. If you enter “firefly06” in the coupon code upon checkout and click the apply button, 10% off will apply to any order only until Monday November 27th (Cyber Monday).
Little late posting this, but you’ve got some time left. Git!
