I apologize for the confusion. I wouldn't know for sure without speaking to their purchasing and/or customer service departments (which I am happy to do, let me know), but it sounds to me like maybe they were planning to set them up as a drop-ship item and then changed their minds and decided to stock them in their own warehouses. The latter is more profitable for the merchant and beneficial to the customer because, especially for a store like MD, they often ship orders the day you place them or the following business day... so you get stuff quickly. These are brand new items that just arrived in the United States.
As the distributor, we receive them from the manufacturer and then distribute them to our network of stores and other aquarium-related businesses. Everything is unfolding just as it should be, it just sounds like the disconnect was in the communications you received from MD. If you provide me with your order #, I can ask them if you would like and try to get an ETA for you. I am checking with MD's account manager here at CV to see when their order was shipped. That way, I can see the estimated delivery date, ask MD how long it generally takes to receive an order and place the merchandise into inventory, and we'll know from there approximately when your order will arrive.
Thank you for your patience in the meantime. I think you'll be pleased with the light. It is more powerful and costs less (once you factor in the tank mount) than the Prime. It has the same form factor as the Ethereal, which at the time, produced the most attractive, well-blended LED lighting I'd ever seen. I am excited for the JUMP as it's right in my price range as well.
