I am totally JAZZED about the new buggies at Kroger.
The supermarket where I shop has those as well and everyone loves them. In fact they've almost all been stolen, that's how loved they are.
The place near me has them and has ALARMS on them that go off if the carts leave the parking lot. I'm always tempted to push one over the line just to see what poor name tag wearing high schooler has the job of chasing down cart thieves.
