priceAdjustment

Either this or price is required. However, this defaults to guide price. A price adjustment is adding/subtracting 5%. Specify a positive number for adding, and a negative number for subtractive. The magnitude of the number is the amount of times to add/subtract 5%. For example, a price adjustment of 10% would be 2. A price adjustment of -15% would be -3.
