Media mail can take up to 4 weeks under normal circumstances. I'm a letter carrier. I have personally waited 6 weeks for and album to be delivered to my home. I'm sorry for your issue.
USPS records delivery delays
Anyone else have issues with USPS taking weeks to deliver media? I can get a delivery from Discogs in a few days or in 2-3 weeks depending on their mood. Currently hoping a current delivery hasn't been stolen.
