Dunno I thought it was pretty appropriate.

Walmart, sells just about everything in one handy location, Nadia sells all technique components.

Walmart, due to the size of the company, can buy in bulk and get special deals that make its goods more affordable then Mom & Pop Inc.

Now its not exactly the same, but its similar. Nadia sells all components at a fixed rate regardless of how hard they actually are to acquire. How is that similar? In both cases there's an uneven playing field.

Now, I'm a capitalist, Walmart has an advantage? more power to them for excersising it. Nadia? more power to her. But as a Mom & Pop adventurer, I'm going to try and take her down anyway I can [;)] Why should Nadia have such an advantage? How many accounts does she pay for?
