Review on Super Mario Balloons Birthday Party Decorations, Set of 9 Pcs by Ana Walker

I have bought balloons through Amazon many times for birthday parties. More often than not, Party City doesn't have balloons that match the chosen birthday theme. I've always been happy until now. These were the weakest balls I have ever bought. They contained no helium and deflated after two days. Usually balloons last at least a week and often several weeks! This time, a balloon didn't even make it home after being inflated in Party City. When I dropped them off, Party City reminded me that they don't stand behind balloons purchased from other suppliers. You've never said that before, but now I understand why. I am VERY dissatisfied with this purchase.
