OP: I urge you to rethink your strategy. It's not all about the price. That's like the people who buy the best ski equipment thinking that will help them ski.
Learning about proper fit, proper foot care and toughening up your feet is the objective. There is no blister proof boot - no matter what you spend.
Recommend you consult some Boy Scouts literature or other sources (REI or other camping stores) regarding foot care and proper sock selection to educate yourself on this subject. Go to the library and get some backpacking books. You will learn about fit, socks, foot care and first aid. You will learn all about moleskin and other options for "hot spots" and blisters.
Also, depending on your ROTC branch and unit, there will be "approved" boots allowed. Don't spend a lot of money on boots that are not approved for wear.
