Having sold online for quite some time, I know people will 'watch' things for all kinds of reasons, including research. So I do realize that not every person watching an item is truly interested in it. However, for those who are, making an offer isn't as difficult as you may think!
The Psychology of Making Offers
I circled around and knew my face was bright red, but I didn't care. I wanted that doll for my WWII collection and I owed it to myself to give this a shot. I walked over to the gentleman the second time and picked the doll back up. I decided that telling him why I was making an offer would more than likely appear to be a 'story,' even though it would have been true (I simply didn't bring enough money with me). So I turned to him, Raggy-Doodle in hand, and said, "Excuse me, but would you be willing to accept $XX for this little guy?" The answer seemed like it took forever, but I know it didn't. "Sure!"
I could have jumped up and down and hugged him! (I opted for the more calm option of grinning from ear to ear and thanking him twice.) I was SO happy to add this little guy to my collection!
the key word: ASK!
SIDE NOTE: I feel like getting all dramatic and going, "REALLY?! Wow! How amazingly generous of you to tell ME what you will give me for it!"... but again, I don't. ;)
