To my knowledge they’ve never offered a coupon code (seems to me they’ve said in the past it’s because they try to keep their prices affordable all year). The exception to this is when they release a new product – often it’s discounted a few dollars when it is first offered. The second exception is their convention prices, which are also slightly lower – so you can save shipping as well as a couple dollars per item.
If you won’t be going to a convention their ebooks are a great deal!
