Westburne Wolseley

I visited this store to buy a copper faucet adapter, I have got two different prices by two salesman. One sales man told me $6.50 and the other sales man charged me $12. The other salesman charged me higher because i did not listen his advice to higher their plumber. This incident occurs on 4th April 2012. They don't have printed prices for anything, they charge whatever price they want on the counter. They have no refund policy.
