NEW YORK — Amazon is extending its annual Prime Day sales and offering new membership perks to Gen Z shoppers amid tariff-related price worries and possibly some consumer boredom with an event marking its 11th year.

The e-commerce giant’s summer deals for Prime members started Tuesday and will end Friday. The company launched the event in 2015 and expanded it to two days in 2019.

Amazon said it would have deals dropping as often as every 5 minutes during certain periods. Prime members ages 18-24, who pay $7.49 per month instead of the $14.99 that older customers not eligible for discounted rates pay for free shipping and other benefits, will receive 5% cash back on their purchases for a limited time. — Associated Press
