We do actually. Our trade program is pretty simple. It's volume based, beginning at ten percent until you reach 3k, after which it becomes 15 percent, transitioning to 20% at 5k. It is cumulative, so you don't need to reach a 3k spend within the first order. We do track it and update as you reach the next level.
The only caveats to our trade program are that items already discounted and Kohler are exempt from any additional discounting.
Let me know if you have any questions.
Thanks!
