I'm kind of appalled by your "don't care" attitude about imposter pins.
Sure, we like to save a buck or three at the parks so we can do other fun stuff, but for many, this is more than just something to do in the parks - it's a hobby. People collect things because it's fun and it's something that matters. AND IT'S SOMETHING OF VALUE.
If you have ever collected anything in your life: Beanie Babies, Cabbage Patch dolls, Star Wars figures - you know that if you ended up with an imposter piece, you'd be pretty upset since you paid genuinely for it.
And actually, your insistance upon not caring about trading bad pins breaks basic pin trading rules (trading bad pins is not allowed) is actually a violation here on the boards. We, as part of the user agreement, agree not to pass on info on how to skirt the rules.
Don't ruin something that is fun for everyone because you don't care what you trade out, as long as your family gets the best.
