Where do you usually get your helium from for parties? There are loads of places online but the prices seem to vary quite a bit, so I'm wondering what the cheapest place would be.
What are qualatex balloons? There seem to be two types, latex or qualatex - no idea what the difference is and googling isn't helping either.
Do you need the sticks or valves or whatever that they try to sell you with the balloons?
And finally, about how long would it take to inflate 50 balloons (of 10")?
