BLF does sometimes have group buys. These can be standard items or slight variations such as different LEDs or different drivers that specially appeal to forum members. Usually, these have to be shipped individually, but the customization or price reduction is justified by multiple orders.
This thread is a good example: Code now public! BLF A6 FET+7135 Light. Short 18350 tubes and Unanodized Lights Available.
