You can find the best price for a large boneless pork loin at your local membership warehouse (Costco, Sam's, etc.) - you can buy one for approximately $12-15.
The instructions for cutting are right on the packaging. I've taken a picture of it with my camera to post here. These are instructions for cutting a boneless pork loin into 2-4 roasts and 12-18 pork loin chops, depending on how large you make your cuts and how many people you are serving.
I own a simple, affordable Weston food saver so I just seal up the roasts into packages, and then put 4 chops into each package. You can use any freeze bag or freezer paper though. Just bundle up tight, and put into your deep freezer for future use.
I got two large pork roasts and a dozen, thick boneless pork loin chops ready for future meals.
