That's the reason why I don't post deals here. It's too public. I'm almost certain that a majority was picked up by either a reseller or some big company...

That's pretty insane. I bet it was a reseller who picked these up knowing they could get double the price. Which is quite sad that this happens. I know I could have done this. But bought 4 that we would need at the moment. Should have bought a lot more last night myself....
Well, if anybody comes asking for reflashing 700+ NICs, that'll be a hard "no"... 
Created a thread here as I couldn't find the one where it has already been suggested
That has to be close to a $100k order...
I've seen this a few times from resellers. Sometimes they will sit on all of those for a year or two and then have to sell at or below cost depending. However, this was a hot deal for the time being that's for sure.
Wish I picked up a few more but at the same time we only rent out servers with 100G a few times a month at most right now still most customers want 40Gbps at most other than our really high end 128 core amd beasts.

Argh, I offered $220 for 5 and they accepted. I should have gone much lower like you.
I bought 5
My wallet hates you. I bought 5, and now I'm about to buy MikroTik CRS504-4XQ-IN Cloud Router Switch too.I bought one of these Mellanox ConnectX-6 CX623106A NICs last month from this seller at slightly higher price; since then, they've reposted the listing with the price lowered to $229 (plus $10 shipping). This seemed like too good a deal to pass up, so I bought another and thought you all might also appreciate a heads up as well.

Edit: as pointed out by GladLock96 below, these are actually Cisco UCS-flavored Mellanox NICs. In my experience, they are not transceiver-locked and work fine with non-Cisco switches, but GladLock96 pointed out and I confirmed with my own sample that they cannot be directly flashed by Nvidia's firmware tool to an Nvidia-supplied firmware image. Caveat emptor, they seem to work fine IME, but firmware updates will be an issue unless you have the expensive MTUSB-1 tool mentioned further downthread.
Yeah it's always a tricky one we sometimes will do it and other times we have lost out because someone else bought everything before our offer was accepted.
We've spent a good 200k I bet over the years from those sellers as well so that could have also had some effect.
For those who are interested in something a bit unusual in CX-6, this one has PPS for PtP tagging.

I guess it's going to include the MTUSB-1 device and some soldering.
I REALLLLLLLY hope not....but if it is, and somebody on this forum gets it working - I'm happy to pay somebody to flash my five cards.
