NEW YORK (AP) — Amazon is slapping a 3.5% fuel and logistics surcharge on third-party sellers using its platform starting later this month amid a spike in fuel prices since the war in Iran started. The temporary charge is effective April 17 for many of the sellers who use Amazon’s fulfillment services, the online behemoth confirmed to The Associated Press in an email Thursday. “Elevated costs in fuel and logistics have increased the cost of operating across the industry,” Amazon said in the emailed statement.
