You do get what you pay for. My husband and I run a Party Rental Company in Albuquerque and yes there are new companies that are advertising $60 for a rental and they are unlicensed and uninsured and God forbid if there is an accident, you are out of luck. Find a good, well reviewed, company and if they are priced well below the average in your area, there is something up. Make sure your bounce house is properly anchored down. Lots of accidents lately due to wind so very important.
