Always check the store policy on mic returns. Many stores will tell you that they cannot accept mics because of health department regulations, which is a lie. There are no such regulations, state or federal. If they give you this crap, tell them to show you the law or regulation in print - they won't do it because there is no such regulation or law on the books in any state in the US. This is merely store policy because they do not want to clean the mic and cannot sell it for new if returned, even if it's on the same day.

Good luck,
