You have the thread "Replace punctuation in an associative array" where 
you can see an example on how it could be possible to work with the

Yeah, I tend to favor to take prices from the database each time, this 
more to keep the prices up to date, as then if someone changes a price 
on a product that price change will get trough at once on all orders 
that are not finalized.
