LOL, I totally left July 4th out of the equation.
These days holidays seem more commercialized and/or politicized than patriotic. A friend of mine says "Memorial Day" should be renamed to "Mattress Sale Day"! So figuring in the the July 4th holiday does indeed bring it down to a 2-day delivery schedule in my area. I have found that 2-day deliveries often get delivered in 1 day if you place the order early enough in the day.
