Looking for some feedback on our new print on demand app

[UglyChristmasS1]

We've just launched our app Printmas which allows Shopify users to integrate print-on-demand ugly Christmas sweaters into their stores.  The app lets upload your store's artwork/designs so you can offer them on ugly Christmas sweaters during the holiday season.  You can upload existing art/designs or create new.   With the ugly Christmas sweater trend growing every year, it can be a quick way in 4Q to boost your revenue, gain marketing presence on social media, etc.   And of course, there is no upfront fees, need to hold inventory, etc.  We have larger sales percentages than Printful and Custom Cat even.  The shopify store sells and we manufacture/print, package, and ship out each other in 48-hours.   If anyone could provide some feedback, we'd be very appreciative.
