Pearl Vision Clerk deliberately left out lower price on lens to get more commission La Crosse, Wisconsin

A couple of weeks ago I went to Pearle Vision in La Crosse, WI to get estimates on the price of glasses.  A female clerk gave me an estimate of $276 for the glasses I was interested in (a 30 percent discount off the original price).

I told her I would think about it and come back some other time.  A couple of nights ago I went back into Pearle and a young gentleman helped me.  I told him I had forgotten the estimate, and could he re-write it (same frames that I picked out a couple of weeks ago).  The estimate for the glasses came to $206.00.  That's quite a difference from the first estimate. 

It turns out that the first estimate with the female clerk was for more expensive lens, etc.  She never gave me any indication that I could get a cheaper pair of glasses; but wrote out the estimate as if $276 was my only choice.  I realized then that the employees get commission on what they sell. 

I am disappointed in the fact that a clerk would deliberately try to screw-me-over so that she could get a bigger commission.  That, to me, is unethical, and I will no longer go there or LensCrafter which is owned by the same people.
