When will my package be here?

So i ordered a video game for my cousin on amazon back on the 15th. I'm leaving fro their house the 22nd. I tracked the shipment and it said that it was shipped on the 16th and arrived in wisconsin and departed from wisconsin on the 17th. I live in new hamshire and I need it by the 22nd. It is being shipped by united states postal service and it is standard shipping. It says the estimated arrival date is the 23rd... do you think the estimated delivery time could be wrong? because i need it before then.. thanks
