Over the past two days I have taken advantage of the CEM Products promotional sales. Yesterday I placed an order for 50% off and within hours I received an email that my items were shipped, including a tracking number with USPS. Then once again today, I made another order for items that I forgot to order the previous day. This time, with a 30% off promo code I received via PM. Then within hours, I received an email that my items were shipped along with a tracking number. I've never ordered items off the internet that have been shipped so quickly. How do you guys do it??? Expect further business from me in the future.
