Hi, I'm sure this question has been asked many times, but please bare with me! I'm trying to send soap to a friend of mine in Utah. It's 3 small bars, with their wrapping the weigh 8 oz and are a little over an inch thick. I had used USPS to calculate the shipping cost and it seemed like a first class large envelope would be the best bet, but now I'm confused because I read elsewhere you can't ship anything over 3/4" thick. :'( what is the next cheapest option? What do you use?
