Postage prices can vary depending on how many samples you are sending in.
Recently, USPS has increased the amount of postage needed for First Class mail (using stamps). Some older tests may contain outdated information, so be sure that you are using the correct amount of postage! For the current postal rates and shipping recommendations, click here.
We do not recommend shipping with USPS First Class as this is the slowest and least reliable shipping method. If you ship using USPS First Class mail, you do so at your own risk.
Please note that if your mold kit reaches us without the proper amount of postage, our lab is responsible for covering that cost and you will be charged additional fees.
