Power Tool Promotion is Dishonest

I purchased a Bosch Cordless Drill at a large Hardware advertising a power tool sale.When i opened up the box i see it only came with one battery. I have purchased Bosch power tool drills before and it always came with a set of 2 battery.If i buy a battery then i am back to original price. Shame on you Bosch Power Tools for being Dishonest and ripping of your customers
