As my long-serving friend and LCBO store manager shared with me last week, "the warehouse is so incredibly overstocked right now, and there's more wine coming this way. Hold off for a bit; prices will drop, they have to."
I can't see there not being quarterly fire-sales, at the very least. And yes, those sales prices should have been the regular prices. The LCBO is greedy and this is much needed comeuppance.
