How legit Is this?

1saleaday.com is very legit.
I'm good friends with the CEO, Ben Federman and we go gun shopping from time to time. I'm Director of Operations for DailyCheckout.com so we sell goods to each other back and forth, I can personally vouch for his products.

What about the stated 90 days warranty?
The majority knows that OEM means NO WARRANTY.
If there is warranty, who is responsible?
