It depends on the bag. Regardless of brand, I look at a bag and determine a price in my head that I think is worth it. If the bag is close to that price point, then the bag is mine. That's why I research my purchases. I think it's important to know where the bags are made, the types of leather/hardwear used, that way I can have some guidance in my decision making process.
Btw this is the way I shop. I've been like this since I was really young. I think I picked it up from my grandpa.
