I've always wondered, do larger companies that ship out a lot of stuff get discounts on shipping costs? Myself, I'm usually able to ship out most games via USPS First Class for less than $2 with delivery confirmation, and the packaging shouldn't cost you more than $.50 if you know what you're doing.
After getting a fair amount of experience with shipping and how much it usually costs, I tend to scoff when I notice a company grossly overcharging for theirs.
