Are they gently used items or brand new things that you don't use but you still have them at home?
Are there going to be more than just the 2 of you?
Do you have catagories for the five items--for instance...one from the kitchen, one bedroom, one decorative.... or it it just anything?
My only concern would be what if you show up with five nice things but someone else shows up with five wooden spoons (over the top but do you know what I mean?)
I like doing stuff like this so I would take part in it!
Have fun and let us know how it turned out!
