Unfortunately (I am a customer since many years ago of this Extra), this BRAZILIAN E-COMMERCE WEBSITE makes SPAMVERTISE under "third-party" servers / PAID SUSPICIOUS SERVICES (aka SPAMMERS, not "regular e-marketing services") called
[supernova.co] (sender: campanha @ news.supernova.co) >>> (added at 2015, Oct 15)
[processcon.com.br] (pros @ processcon.com.br) - PART OF SPAM NETWORK, SPAMBOT, and SCAM SERVER
[twebus.com] (sender: parceiro @ twebus.com) and from many BRAZILIAN SPAM SERVERS / PAID SUSPICIOUS SERVICES.
If this (spamvertise) continues, I will NEVERMORE BUY ANYTHING in the Extra and I WILL REMOVE MY REGISTRATION - the 2016 year is already coming, and the Carrefour (the main rival of Extra in the Brazil, and who NEVER SENT ME ANY SPAMVERTISE) may will get back the e-commerce website and that's where I'm going. That is it.
