It's a price elasticity of demand thing; there's virtually limitless supply so they can put whatever price they compute makes the biggest total revenue.
You'll note they quite often have these few day price cuts to experiment with how demand is affected so they can compute corresponding price elasticity.
To sell another copy they only need to pay for a trivial amount of bandwidth and server processing (and any contracts for the sold title). Edit: Of course personnel costs are also somewhat proportional to quantity sold.
