Let's consider Walmart! What are some of their resources and capabilities?

We always think that Walmart has the cheapest prices and a great lost cost provider strategy but they may be losing their edge. But couldn't someone like Amazon provide cheaper prices. They sell online and don't have the physical retail locations to pay for. That's one benefit to the virtual marketplace...less overhead on buildings and utilities and what not. Customers definitely have to give up some to get those cheaper prices at Walmart. The customer services isn't the best. The lines are always ridiculously long. They decor isn't all that attractive. I guess it's a give and take. I think Walmart is trying new things to maintain their low cost provider title. They have savings catcher now that checks for the lowest prices across all retailers in the area and if it find a lower price, Walmart gives you the money back. That's great for busy folks that don't have time to compare prices and shop different retailers.

Can you think of any changes Walmart could make to maintain their competitiveness?
