I don't agree you cannot have a two-tiered product. A lot of businesses have a good-better-best option. For example, a bargain basement in an upscale store.Isn't the point that if I say something, they don't get to abuse the next person? Isn't that the point of the feedback system?why dont you just write a good review and be done with it. why are you worrying about all of this, do the right thing, take the high road lad..
On the other hand, we have learnt something... we can't sell a two-tiered product. So everyone gets the exact same product, no matter what.

The critical thing is how you present and control it.
