Online signups can be super clutch if you live (edit: I meant if your store is in, but let’s be real, if you’re a TL, you pretty much live at your store) in a densely populated area and don’t have any super nearby sister stores that you’d be splitting the signups with.
Don’t forget, you can take the registry iPads out of kiosk mode and open the browser and guide guests through the online signup process if they’re tech-challenged or they don’t have checks but know their account and routing numbers. They can’t shop with it in store until the card arrives, but they can shop online and do OPUs right away.
