My guess is they were referring to demand of this new LED. If the builder of the FT03 did receive the leds, they may have decided to allocate those particular leds to a different company’s product. Or the FT03 builder may have been promised a shipment of that led which was later sold to a different manufacturer.
Weird. I see that banggood has a ft03 sft40 ready to ship, but it says that the coupon code works on a different sku number.
The one that the code works on says completely out of stock with no estimated arrival date or anything.
