Stefan, We are sorry to hear that you did not receive the discount you were promised and we really wish you would have contacted us so we could have corrected the situation. The 50% discount in question was for honorary members of Team Second Skin. This was back in October when we offered the discount and the expiration date was 1 month and was posted in the email that was sent out. I did offer you the 25% discount for being a team member. As you can imagine, I deal with many people on a daily basis and did not recall our previous email conversation when you came by. If I remember correctly, we had a nice conversation about your goals and we showed you the great deal we had on the 30 sq ft packs of B-Stock Damp Pro. You said 30 sq ft was too much, so we broke open a box and let you get what you need. This is something that we never do because it leaves us with a partial box, but hey, we wanted to get you setup right and at a great price. I then got busy on the phone and Max completed the sale. If you would have reminded either Max or myself about the discount, we would have had no problem giving it to you. With that said, credit for $22.73 has been issued to your credit card which is 25% of your purchase. Ken
