Amazon will tighten Prime delivery requirements in Germany from 7 September, affecting FBA and merchant-fulfilled sellers. For standard-sized, lower-priced products, 15% of orders must arrive within one day, up from 10%, while 50% must arrive within two days, versus 45% previously. The requirement for 80% of orders to arrive within four days is unchanged. Amazon said the changes would improve the Prime customer experience. (Ebrun)
