I agree with you, LadyJaiven. I think it's common courtesy to give thanks to a person who has done something nice for you. Your post is actually very timely for me, since I have started to get quite upset about the lack of courtesy and consideration by some people... I'm glad to see that I'm not the only one with these "old-fashioned" (?) values. As for the merchants, just look at how many products there are in the Marketplace. Being nice and polite could be one area where you can stand out from all the other sellers. :)
