A Helium Shortage?? I thought the Company's were crazy... But there really is a shortage. This is the first time I've ever needed to rent a Helium tank so why should I expect anything else?? Just my luck. The guy at the Helium rental place said to rent a tank that would fill 50 balloons would cost $50 bucks one dollar per balloon plus the cost of the balloons which I already have..(Cow print balloons of course) So with the cost of the balloons and helium it would cost about $1.35 per latex balloon.. Yikes So I found this little Balloon Helium Kit at Walmart for $20 bucks and will fill up 30 balloons.. So I bought 2 and called it good.
