[READ MORE: Three signals from a four-day Amazon Prime Day] For the past several years, Walmart and Target have hosted their own summer sales blockbusters that are timed to compete with Prime Day.

Target made its Circle Week announcement last Monday as part of its back-to-school promotion events. College students and teachers will both receive a one-time 20% off storewide discount with Target Circle. The company is also holding the pricing offered last back-to-school season.

Amazon.com Inc.’s Prime Day is slamming into President Donald Trump’s trade war, with ever-shifting tariffs prompting some brands to sit out the summer sale and some shoppers dropping hints they plan to pull back.

Best Buy’s sale runs July 7-13, overlapping with Amazon’s extended Prime Day offerings July 8 to 11. Target’s Circle Week runs July 6 to 12.
