I agree with what was said about toys. It kind of creates a tunnel vision effect. Your brain and eyes are completely set on the toys when chances are that there is a diamond sellilng dirt cheap right in front of you. I don't attend that many yard sales, estate sales, etc. but when I do; I don't go looking for anything in particular. I take my time and usually look for items that have great eye appeal and it's worth buying and taking a risk that I may or may not be able to flip it for a profit.
