What could be an explanation for this economic puzzle of lower turkey prices during higher demand?
Definition
1: The loss-leader explanation (low prices advertised for high-demand items to attract customers, who then purchase other goods.)
2: A related supply-side explanation has to do with the breakdown of tacit collusion. Basically, if there was ever any informal agreement among competitors to keep prices a bit higher – that is, to avoid a price war – there’s greater incentive to “cheat” around Thanksgiving and offer big discounts because such a huge customer base is available.
3: Great price sensitivity among consumers (that is, greater demand elasticity) is another explanation, related to changes in the composition of customers, changes in their preferences, or more time available to price-shop around the holidays. Consumers might search more during high-demand periods

basically, huge demand and observant customers allow producers to get away with lower prices
