Carrington Lighting

I went to Carrington to select some light fixtures, about a month later saw a different light fixture that they put on display at their showroom. I talked to the sales rep, and she told me that my original light fixture was a special order and cannot be returned, otherwise it would incur a restocking fee. The original fixture was on back order when I first inquired about exchanging it, so that light was never mounted. It was still brand new in box at their warehouse. When I first picked the original fixture, I was NEVER TOLD THAT WAS A FINAL SALE and no changes can be made. I talked to the manager and she insists that I must pay a restocking fee of 15% to send it back to the manufacturer, since the light was about $1200, I had to pay almost $200. I asked if she stock any lights in her warehouse, and she said that 90% of the lights HAD TO be special ordered from the manufacturer. IF THAT IS THE CASE, WHY DON'T THEY INFORM THE CUSTOMER INITIALLY that there would be a restocking fee if exchanged or returned? I wanted the new light since it matches better to our other bathroom fixtures, I would've picked it if I saw it in the showroom initially. I'll be taking my future business elsewhere for sure. I also felt the sales rep had a bad attitude, she seemed like annoyed when you had to inquire about the different lights.
