When you go to a retail store, you will find the prices and offers there, but a good move would be to check the website of the store as well.
Some sellers place some offers online or show lower prices. If you point it out at the counter, this will give you an opportunity to bargain at the store as well.
This might not work at all places all the time, but at some points the store will agree, because you are allowed to order purchase of the same thing you collected at their store.
