It depends when the item gets taken to the post office. We post items out and they’re handed into the post office about 4 ish and first class generally gets there next day BUT it’s not guaranteed and Fridays is always a bad day post as everyone wants their stuff by Saturday so there’s lots of post and it’s generally 50/50 if it gets there Saturday. We do RMSD but even that doesn’t guarantee next day before 12 on a Saturday but we can offer an option for guaranteed before 12 on a Saturday but it’s expensive with RM.
