I sent them a message to know what will be their advices, I'm interested to know what people will say here

Please post reply if you get it

I also sent them email asking to sell my D3s asap.

Here is the answer I received yesterday night :
Hello, thank you for your inquiry to sell your miner(s). This only applies to your hardware that has already arrived at the Giga Watt facility.
You can choose to sell your miner(s) with PSU on your own at verified online marketplaces such as
www.ebay.com or
www.amazon.com, or alternative classified sites such as
www.craigslist.com,
www.oodle.com or
www.gumtree.com. You can also choose to have it sold on consignment for you at sites such as
www.coinminer.com where they will facilitate the sale and pay the consignor a percentage of sold price.
If you choose to sell them direct to a customer, we will require you to provide your customers name, email, and ship-to address information. Please note that alternative classified sites do not have refund protection such as verified marketplace sites or consignment sales sites, and are to be used at your own discretion. We will provide free domestic ground shipping, and a tracking number within 24 hours. Also please be aware that equipment prices do vary, you will want to do some market research to list your equipment at competitive pricing.
Thanks again for your patience and let us know if you have any further questions about your selling options.
They tell you to be cautious about the lack of refund protection of "alternative classified sites" but nothing about ebay and the people using your miner and sending it back within 10 days...
