"Hi how are you, didja have fun shopping, do you have any coupons or cartwheel today, will you be saving 5% with us today"
Vary a few words here and there and personalize it for your regulars, but that's how you work in Cartwheel every time you interact with a guest checking out.
"What's Cartwheel?"
It's a part of the Target app that allows you to save on hundreds of items in store. (hands are moving, you're still ringing in their stuff)
If they want to download it, suspend the transaction, tell them that they can move to the side, or we can hold their cart if they want to have a seat in the Cafe and enjoy a snack while they get set up.
If they have only Cartwheel specific items, like maybe shoes for the family are 30% off, and it's a quick transaction, they STILL have to download it. No, they didn't read the sign, yes, they're going to resist. Offer to suspend or if you've only rung up a few items and they're going to DL the app, void everything and move them to the side. Tell them you'll show them how to use it when they come back. But be nice about it, you have to be diplomatic in retail. You come here to bitch, but out there, you have to be a freakin' UN ambassador.
Anyway, once they download it and set up their account, THAT's when you scan the suspend ticket and start back with them. Yes, they have to get back in line. But that's just the way it is, it's one time only, get it out of the way.
That was my approach to Red Cards too - sign up now, get it over with, put money in your pocket. I ended 2017 as #1 red card seller in my store without tricks or lies. And you all know, there's that one TM who lies like a rug to get old people to sign up.
