I purchased a SM4U originally costing $139.99 and they have a promotional code for 20% percent off the price which is WINTERSALE2 which includes all accessories not only mouthpieces. My total is now $111.99 after the discount code. Then you can combine this coupon code with an additional promotion when you join there free rewards club getting another 15% off the price which then cost $95.19 less then the silver plated SM4U which retails at $99.99. Also did I mention free shipping?

Great way to get a new accessory!
