They should. I put it in my cart and it shows $15.99. Are you a recent subscriber or have you been subscribing for a while? I know the discounts don't apply until you get your first subscription shipment.
Ah, gotcha. Yes I am a recent subscriber so I'll check back when my shipment arrives. On a side note Hawkmoon, as a long time lurker on the forums, thanks for all the info you've shared! :D
