Keep in mind though, the LCBO charges a standard markup on this stuff. So if anyone is manipulating the prices like that it's the suppliers, not the LCBO.
The Auditor General, Toronto Star columnist Martin Regg Cohn and dozens other critics might see it differently. From the TO Star:
Here’s how the bizarre policy works: The LCBO sets a price range for a particular class of wine. Suppliers bid with a proposed retail price, then work backwards from the LCBO’s fixed markup to arrive at a pre-determined wholesale price.
Absurdly, if a supplier’s suggested retail price (and therefore his wholesale price) is deemed too low, the LCBO goes back to the supplier and offers to pay a higher wholesale price so as to bump up the final selling price.
