What could be causing the error (wrong price)?
Somewhere in the code, the variable is not initialized correctly. Or option 2 - you forgot to normalize the price(NormalizeDouble())

I doubt this is the case as it does not always happen, rarely and not systematically. It is due to some price factor, but which one?

So what's the problem? As soon as error number such-and-such occurs, print(" MyValue = ",MyValue);) and it will immediately become clear what it equals.
What is the value of MyValue?

How do I know what your variable equals? :) Let the printer show you what it equals.
