I went to OSH to get my daughter a set of keys for the house and gate. While there I picked up an ad that said from Saturday to Saturday they were haveing a sale and were giving 15% off. Because of this I picked up some energy saving bulbs and went to the garden department and found a plant for the patio. At the register the bill came to $39.00 I asked the cashier what about the 15% she said, 'Ive already rang it up'. You can take your stuff to customer service and they can fix it for you.
There was a day when the person behind the counter would have told me about the sale as soon as I stepped up. I was going to buy two more plants but I bet I can beat the price anywhere.
