The Satchels for Fastway do not display an exact price. Yes, we are aware that the API rate returned is not accurate.
I will try to explain what is happening:
The lowest Satchel price may be $7.70 and the highest Satchel price may be $11.10 this is what the fastway.com.au Website returns.
I have a screen shot attached, which displays this information.
The Fastway APi does not supply the exact price. It provides the lowest price and the highest price.
The Satchel price on your website, should always supply the cheapest rate available.
