Social Dilemma-Does the Phrase "Do You Want This" Imply That It's Free?

So today's social dilemma has actually caused a little controversy between a friend and me.  Certainly nothing that would have a major impact on our friendship, but something I thought was a little off.  Okay, here's the deal.  A friend of mine recently sent me a picture of a scarf with the caption, "Do You Want This?"   I liked the scarf, so I gave an enthusiastic yes and thank you!!  Fast forward to the next morning when we're making plans for me to come over to her house, and my friend says, "you can have the scarf for ten bucks, I paid $30 for it."  Now, with the words, "do you want this?" I assumed it was free.   We were two friends talking with each other.   It's not a a marketplace.   My friend said the phrase "do you want this?" is just to see if I was interested in the scarf and then we could talk price later.   I still think it means it should be free.   What do you think?  What does the phrase "do you want this" imply??  Free or a price attached?  Let me know what you think on the TRY Facebook page.
