My in-laws buy things and then change their mind a year later and re-buy something different, an example:
Last year they bought a brand 2 new umbrellas for their patio set, they sold one to their neighbor who in turn gave us their smaller version.
This summer my in-laws decided to cover their deck, there for not needing their umbrella and giving it to us! The smaller version we got from their neighbors will be going in our yard sale this weekend! YEA!
