One of my coworkers, who got married a few years ago, told me that they received a bunch of strange wedding gifts because they were items they hadn't registered for and the guests expected them to need. Examples are blenders, coffee makers, quesadilla maker, etc. This coworker recommended that I find a way to add some of these items to my registry and mark them as "fulfilled" if I did not want guests to purchase them. FI and I already have a waffle maker, blender, and coffee maker that we love, but I'm concerned that this is rude to mislead guests.
Should I add some fake items to the registry just to mark them as "fulfilled" or leave it alone and try to return any unwanted gifts?
