Variable Prices at outlets

I just send something through Leopard.
I asked its cost from PWD's branch and Soan Garden's branch.
The PWD's was charging 200 more than the Soan's.

They blatantly say that every branch has its own price list. Both outlets/franchises are at distance of 5-mins drive from each other.

This is really pathatic the company has no mechanic to keep a check on what is going on in its outlets/franchises.

This reminds me of what the EasyPaisa representatives do on withdrawal: they charge 20 Rs. or so on their own.
