First, even though know it's not the actual client, I would edit out the name of the store you mentioned.
You're not necessarily missing anything. Conduct your interaction with the floor associate, and make sure you express interest in an item within that price range, certainly not under. IF there is a second point of purchase, ie; register, etc., and it's a different person, take it through to the end, just before the actual point of sale. So basically, if it's the same person, only one interaction. And if it's a different person, all you have to do is listen the second time, not bring it up. I've done a couple, and there was only one with a seperate cashier area/different person.
