Procter & Gamble – Dawn platinum bottle appears low in product

I ordered a 32.7 oz. bottle of Dawn Platinum through Amazon last week.

The bottle appears to have less product than should be there. Is this the appropriate empty space at the top of the top? There was no product outside of the bottle. There is a two-inch empty space at the top of the bottle.

If this was an error in production, I would like to get a coupon for additiona Dawn. I do enjoy using it.
