If time is of the essence, you may want to check with Marathon before ordering. I saw on another forum earlier this month that a poster's wouldn't be ready until July if they had to be shipped but could've been picked up after three weeks. I don't know why the difference in times.
Headwaters are another option. When I separately ordered front and rear sets it took about two weeks to get them. They're supposed to be quite similar to Marathons as the owner got his start there.
