Shopify stock soars on new partnership with Amazon

$Shopify (SHOP.US)$ is opening the day up 7% on this story from the morning:
$Amazon (AMZN.US)$ will be releasing an app in Shopify’s app ecosystem that will give US-based merchants who use Amazon’s fulfillment network the option to add Buy with Prime into their Shopify Checkout processed by Shopify Payments.
Shopify merchants will have the choice to offer their products to Prime members on Shopify for the first time ever while continuing to maintain 100% control of their brand and their customer data in Shopify’s admin.
