International Electronics Deceptive Selling Practices on Camera Lens Sunrise Florida

I was on vacation in Florida to go on a cruise.  I took my wife shopping at Sawgrass Mills Mall.  I saw that International electronics had an ample supply of camera lenses and I was specifically looking for a lens that would let you take good close ups and an had a wide angle.  I specifically asked for a low f-stop lens. 

I asked to see a Nikor lens and after showing me tht lens, the camera salesman directed me to the store manager who lowered the price of an Axer wide angle lens that also doubled as a macro lens.  

He started out wanting $900 for the lens and after realizing I wasn't going to pay that, dropped the price several times until hr came down to $500. I thought all through my cruise that I had made a good purchase until when I got home and downloaded the pictures and discovered that most of them that I used the new lens on had a "tunnel" shadow look to them.  It was like you were looking out of a telescope at whatever you were taking the picture of.  

The store had a 7 day exchange warranty but that wouldn't work for us as we were going on an 11 day cruise.  This lens is available (he sold it as a composition lens) for less the $20.00.  He showed me a Axer website where the lens was valued at $999.99.  This store knowingly sold me an inferior product at an exorbitant price.  I will never do business with them again, and want to warn others about their scam.
