Because you dont use prime... just pay for 2 day shipping and if it takes 3 days then you gotta email them and you get your money back.Why does Amazon advertise 2 day shipping (Prime Member) when 90% of what I order takes 4-5 days to receive.
Talking about Optics Planet ... they are giving me the run-around just because i didn't use a US email address for ordering... and I even paid with a faster shipping method so i could get my stock adapter quicker. First and last time I ordered from this place,no other shop has that issue...
