I signed up to dealchecker a couple of months ago, and have only ever received the travel deals that I signed up for. The site does what it says on the tin, and I can't fault the mailings that I've been sent.
The comments below all refer to spam so I wanted to make clear that this is something we take very seriously at dealchecker.
We never send unsolicited mail, so if you are having problems with your dealchecker mailings, for example you don't think the unsubscribe link has worked or you don't remember signing up to our service please email us at email@example.com
We'll take you straight off our mailing list and we'll want to get to the bottom of the issue too.
I understand about the unwanted e-mails but it still gives the buyer a chance of a good deal on accommodation if you want to book I will review my final rating untill i no longer wish to receive mall from Dealchecker.
