are Tuesday's the best day to ship on PH? Seems like a total crap shoot

Honestly I don't believe in a best day to ship simply because if it exists & it is known about the best products would be shipped then & it would be more competitive & harder to have a successful launch. Oftentimes it's a matter of luck - it's better to focus on making a polished product than finding the right time to share it, in my opinion.
