It's like sellers advertise it but you don't get a package for at-least a week. I'm not trying to be a dick or anything, but man if I'm paying $10+ for shipping alone I should get it atleast quick enough.
I placed a order monday, seller marked it shipped 2 day priority. It's literally about to be friday and no sign of it, most likely gonna come next monday.
That's just my rant
The point in priority is to get it in 2-3 days instead of 3-5 with first class. You may not get your packages in those times but you are the exception.
