Online Access Code

I purchased the printed version Physics, 10th Edition by Cutnell from Wiley, thinking that the book would come with an online access code. However, upon receiving the book, there was no access code included. Do I have to buy the online access code separately? The only options I see are to buy it with the textbook, whether online or in print, but I already have the textbook and don't want to pay the spiked price. I just want to buy the access code to do my assigned physics HW problems!!
