I started keeping a calendar for that very reason. I was concerned about the "2 day priority" packages taking so long, but I understand that is how it goes. Here are my last 5 orders:4 of them were priority "2day" from Southern Cali to the southeast (TN):2 of them took 3 days, not counting the day it was mailed. For instance mailed on Monday morning and showed up Thursday. 2 was 4 days, not counting the day it was mailed. For example, mailed Monday morning, arrived Friday.So, not counting the day they were shipped, 3.5 days was the four order average from So Cal to TN.My last order was a letter from N Cali to TN, which was mailed first class. It took three days, not counting the mail date. Hope that helps.
