USPS Retail

I've always wondered why the USPS doesn't more heavily merchandise their stores. They have to make money just like everyone else. They have awesome products and services:

• Collectible stamps
• Shipping materials
• Shipping services
• Telephone cards
• Post office boxes

They should also have: candy, soft drinks, and other convenience store items, as well as self service photocopiers, computer rentals, and wifi online access.
