Got a call from this number. The caller did not leave any message.

I received a text from 775 400 9005 wanting to thank me and give them a call at 877 225 2304 for my $100 gift card.
I called the 877 number and the gentleman wanted my name.  I gave him a name and then he requested my address.  I did not give him my address.
I then asked how I was selected to receive this gift card.
The gentleman informed me that I had visited a web site that qualified me for the gift card.
I then asked if all I had to do to receive the gift card was give him my name & address and then they would mail it to me.
The gentleman said, "Yes" and then he hung up on me.
Can we say - Scam!
