What the price to sales ratio tells you

Market value divided by revenue over the last twelve months. Useful for companies with little or no profit yet, since sales are harder to make negative than earnings.

Ignores margins entirely. A software company at 10× sales with 30% margins can be cheaper than a grocer at 1× sales with 2% margins.
