I got my SDS200 brand new with warranty for $465.
I got a Chase Freedom card in December which gives you a $200 statement credit if you charge $500 to the credit card in the first 90 days. Then each quarter they give you 5% cashback on specific categories and in December it was for paying with Paypal or Chase Pay. I bought it from Scanner Master which accepts PayPal, has free delivery, and doesn't charge tax.
So I paid $700 (no tax) - $200 - 5% of $700 ($35) = $465.
