Whether they are a good organization or not, I can't really tell you... but definitely not all people who belong to the ACLU are anti-Christian, and definitely they have done some good, mixed in there with some less good things... just like anyone. We do good things and bad things, and hopefully the good wins out.
According to the United States Postal Service, priority mail takes 1 to 3 days to arrive at its destination. The length of time varies due to the distance based on the shipping point and the receiving point.
Even for small envelopes and light packages, USPS Priority Mail 2-Day is a better service than First-Class Mail. The price point is slightly higher, but delivery is much quicker. First-Class shipments may arrive in a day, or three days, or seven days. In contrast, Priority Mail is delivered within three days in most cases. Additionally, Priority Mail becomes the cheapest option for sending envelopes or packages that are heavy. Flat rate shipping means no increase in price with a heavier weight.
