Not sure what you are getting at really. The ad on alibaba from eshine is listed at $100-300 each.
To get anywhere NEAR $100, you have to order ONE THOUSAND units per month under contract. Per MONTH!!
I ordered 6, direct from Eshine and talk to the sales rep Laura on almost a weekly basis still, as we have become friends. I ordered 6 units, but didn't pay $400 each. I got them for $200ish plus shipping costs. What they sell them for to anyone else may be different. Some people may pay $250-300, some may pay $150. Not my business. My actual invoice was (if I remember correctly) around $1,500 with shipping. Shipping from China isn't cheap.
Also, I've had mine for quite awhile. An just like anything else that uses LED, prices are rapidly dropping.
I'm not mad or upset at your post in any way. But I also did lots of research on them before I purchased, and I knew exactly what they were, and where they were coming from.
