Massdrop is a website that requests bulk group buy discounts on various items including headphones, keyboards, mice, and more. I check every once in a while, and I found this LED gaming mouse. Massdrop basically negotiates a discounted price on a bulk item purchase chosen by the community, and has users pledge to pay when the drop is scheduled to be ordered. When Massdrop receives the order they mail it to you.
I’ve used Massdrop a few times. If you’re not worried about getting the product immediately, it’s great for getting some good deals. I picked up a pair of White Audioengine A2+ Speakers for $194 from their Massdrop back in December.
