A little explanation on that ebay ad...
We don't normally sell on ebay as the seller fees are high and reduce our margins.
The ad was auto-generated six months ago by our ecommerce site and posted as an experiment to see if it would draw attention from ebay game buyers who don't frequent forums and aren't as familiar with ColorDMD. The ad mirrors the product page on our site which is why it didn't specifically call out ColorDMD in the title of the product listing.
The flash sale that happened yesterday came as a complete surprise. Although being an ebay member for many years, I didn't even know that was a thing. The ad hadn't drawn much attention and to be honest I forgot it was even running until we started getting multiple hits late yesterday.
I didn't find out about the flash sale until it was almost over and am still puzzled how ebay was able to offer such a large discount. Half the discount came from seller fees we were charged but the other half seems to have come from ebay directly in the form of an economic stimulus package.
Congrats to those that were able to get a great deal!
