Here is where we got ours...
We have two robots to build ...
This place had a box of 15 delivered for $49.95
They got them to us in a reasonable amount of time.
(Seattle is no place to find pool noodles in January...
)

They were decent to work with and we had no problems.
This is about 3.33 each delivered.
Watch out for other online deals... cheaper noodles but the cost of shipping is really large.
thanks GOOD LUCK!!!
