I have unsubbed from their mailing list more than three times now, and they still send spam mail anyway!
Just stop it, stop!
And no, I'm not reaching to your customer support as they were unhelpful when I did reach out to them.
ALSO, the discount code I got after subscribing to their mailing list did NOT work. It was a SCAM, if not then at least declare that the code can't be added to already discounter items. just terrible all around.
PS: Stop sending crap mail, please.
