I really want to buy a computer case from Computer...

I really want to buy a computer case from Computer Alliance, however Josh told me that you can't actually inspect the cases prior to buying them, and if you do buy a case, and you don't like it, then you can return it for a 20% purchase fee, which for a $300 case if nearly $60! To return a case you might not like.. that you can't even see in the first place. mindblown.... How many people just blindly buy cases from looking at the pictures online? :/
