I think folks can understand percentage off. A quick glance through the "member news" indicates most do it this way. Here is a rough draft of the presser I am doing if you're interested. In realty, I think the customer needs to understand the discount only pertains to the artist mark-up.
------------------------------
Remember the code.
In anticipation of the coming holiday shopping season, Joseph C. Hinson is pleased to announce a "30% for 30 Days" discount offer. From now until December 2, 2014, get a 30% discount on any of the 525+ images for sale in his extensive portfolio.
The discount code is SVPCYC.
"Basically, you do your shopping and then hit the check out arrow. When that page comes up, there will be a box for the code on the right hand side. Just pop the code in and it will take care of the rest."
SVPCYC
"The cool thing about this," Hinson says, "is that you get the same discount off any print and any size. I've always been a big fan on the metal prints, which are also some of the cheapest by cost. So right now you can get a metal print of any size for basically a third off the regular price. But the discount is good for everything, so you can also choose a regular print matted and framed for the same thirty percent off."
It is important to note that the discount applies to the artist markup only. The pricing of the frames, canvas, mattes, etc are set by Fine Art America and the discount does not apply. "This special comes off of my mark-up," Hinson notes. "The folks at FAA still have to use the same materials and they still do the same superb workmanship on packing and materials. It's one reason I am so big on metal or even canvas prints. They are less expensive to put together."
Regular Shipping & Handling rates also still apply.

Not many people were explaining the mark-up on the member news. A few even forgot to give the code when announcing it.
