Your friend tells you that their SO is giving you a present for Christmas. You like her SO, but you weren't planning on getting him anything since you aren't very close. You ask her what he would like and she sends a list that he made up and sent to friends and family. You pick an item and buy it, but you don't have the chance to meet up and exchange gifts until after Christmas. Before the exchange, your friend mentions to you that someone else already got him the same gift and asks if you can return it and exchange it for something else. What do you say/do?
This situation aside, what do you think about people sending out Christmas lists with specific items on it, with links?
