hi, there, your sales promotion is really attractive: 2-5 units: 5% off 6-9 units:10% off 10+units: 15% off. We do save more than last time we bought 20 units. So exciting! This time we will buy 100 units for 10 different styles. i've contacted amanda. i just want to leave my review here to say thank you and let other customers know you are doing good.
