At least for the time being, it appears that the big brewers are phasing out their electronic IRC scanbacks in California, the very way beer has been sold in chains in that state for years. Brewers lately have been preferring mail-in rebate offers, which have the benefit of low redemption rates. If brewers can hold, domestic scanbacks on bigger packs will expire soon out West, driving a price increase for 20, 30 and 18 packs, a de facto price increase which benefits the brewers 100% since they pay 100% of the scanbacks. If it holds, it could help out fledgling Corona and Heineken .
