A friend recently sent me a great quote "Taking back your ex is like buying your shit back from your own garage sale." While I find this to be true, it doesn't have a lot to do with any of the Las Vegas Goodwill stores.
Luckily, I love the Goodwill stores in Las Vegas because they have so much weird crap! Go whenever you can and look for the strange & unusual if you're into that. I once found an amazing 2 headed goat. The amount of creepy looking house-hold items at Las Vegas Goodwill stores is far above the national average.
