Hi, the Reef Breeders June/July Group Buy will start on June 21st, and end on July 1st (we will NOT accept orders after July 1st). To join the group buy, simply email us at GroupBuy@ReefBreeders.com with what you want to order, and which optics you want on your light(s). We will reply with a link, which has your order on it. From there, you can checkout via PayPal or credit card. The fixtures will ship in about 2-3 weeks, however, allow until the end of July for us to ship the lights. In past group buys, the fixtures usually have gone out in the third or fourth week. We will be applying new methods to speed the shipping time up, and we have also been assured that our fixtures are the factory's top priority, and they will be made faster this time, but please allow for delays. Also, to clear up some confusion that occurred in the last buy, the fixtures come fully assembled, with a remote, hanging kit, and controller. And, for a custom layout, you cannot change the channels in any way, but you can change which color LEDs are on each channel. Shipping is included in the pricing of everything except for LEDs that are not purchased with a fixture, shipping will be an additional $5.10. Here is a list of the prices: Here is a template for the information that should be included in your email to us: Email Address: Your Email Address Full Name: Your Full Name Fixture: The Fixture You wish To Order Options: The Optics You want on the Fixture, and/or any customization you want done (customization is $10 extra, and optional) Parts: What LEDs/Optics do You Want, if Any? Thank You, we look forward to running another group buy with you guys, and we will continue to do so in the future.
