Do not sign up for efooddepot.com. Save yourself! I signed up because I moved to a new city and couldn't find this cheap (but delicious) Vietnamese instant coffee mix anywhere in a store. When they email you, there's a fake option to unsubscribe at the bottom. It's just underlined text that says 'unsubscribe'. There's no real option to unsubscribe. And there's no way to deactivate your account either. I also tried emailing them through their 'contact us' page, but they never responded to me about how to deactivate my account and to be taken off of their mailing list.
Unless you want spam and the possibility of a virus, do not sign up. This site should be shut down.
