I used to be totally on board with Cartwheel when it first came out. I used it, I would love educating guests about it, and guests themselves were excited about it as well. But as the app has matured, I feel totally the opposite now. Once we started posting signs advertising Cartwheel, that's when I think the biggest problems began. I have to help SOOO many guests whom buy merchandise, thinking it was 20% off, only to have to explain to them that it's when you use an app. Having them step out of line so they can download it, log-in, and then add the deals, and then step in line to fix such a minor thing is a huge waste of time.
Also, I fix so many issues for guests that DO have the app, but forget to tap "add" to add it to their list. I've said this before but, what on earth is the point of that? If it's there, what's with the extra steps? If it's there, then the item is on sale!!! Cartwheel should work so that, if a deal is there, then you get it on sale. Period. ALL the deals are added to your barcode. That way, instead of Cartwheel being a game, you can just shop from it like a shopping list, which eliminates that room for error. It's such an old fashioned business tactic, to make a game out of shopping. It's like grocery stores that do those bullshit "stamp" programs so you can get free cookware. Take the costs for the bullshit games, and just make shit on sale please.
This past holiday season was the worst for cartwheel and it's what made me completely change my mind about it. I swear that nearly every other guest at GS was there to fix mistakes with cartwheel. So now you have dissatisfied guests frustrated with the app, and frustrated guests whom had a longer wait in line. Yeah great, that sounds totally effective towards sales.
