Missed the 160 LED video light bundle? Apparently LinkDelight is slashing prices on a number of items including two different 15mm Rails with quick release camera mount and tripod base plate. [Thanks Viktor]
One of these sets looks like a part found from a Fotga rig. If you just need to get started with a simple set to support a basic follow focus or to mount other 15mm accessories, check out the two different sets following the link (click here)

Also noted in the comments, they are practically throwing away their DSLR Follow Focus systems at 42% off. The LED light bundle sold out in minutes, so I don't expect these prices to last.
Other people are finding deals on a variety of items today, so it might be worth checking out more Photo / Video products from this seller.
