Costco Wholesale Corp. COST, +3.10% said late Wednesday its April net sales rose 13.9% to $17.33 billion, from $15.21 billion in April 2021. Same-store sales rose 12.6%, the retailer said, with e-commerce sales up 5.7%. The month had one fewer shopping day as compared with last year's thanks to the later-than-usual Easter holiday. That trimmed total and same-store sales by about 2% to 2.5%, Costco said. Shares of Costco edged lower in the after-hours session after ending the regular trading day up 3.1%.
