Mercari is running a limited beta program from March 19 to May 14, 2026, offering tiered selling fee discounts to select high-volume sellers based on their cumulative sales during the eight weeks prior to the program start, with no opt-in required and tier status trackable via a profile page progress bar. The promotion is off to a rocky start, with multiple sellers reporting 404 errors when clicking through from their invitation emails to view their tier status, and Mercari appears to be testing different tier structures with different sellers as part of the beta. The move marks a return to a format Mercari tested back in 2021, and comes as the U.S. marketplace reported its first-ever full-year profit in fiscal year 2025 following a leadership shakeup and fee structure overhaul that began early last year.
