"As part of Prime Day promotions, Amazon has leveraged its grocery chain to offer in-store incentives for Prime members: last year shoppers who spent $10 received a $10 Amazon credit to use on Prime Day, and a small, somewhat random selection of items (boneless chicken breast, RX Bars, Waterloo seltzer) were discounted. The company has also been advertising lower grocery prices for Prime members to drive sign-ups; for 2019 it promised deep discounts on select popular products plus an additional 10 percent off hundreds of sale items, though past deals have felt limited and inconsistent." - Ellie Krupnick
