I will be the first to admit when I don't know exactly the difference in photographic equipment, but not Carsand-mosher Photographic.

I purchased a cir-polarizer almost a year ago. I was over charged for the item and was extremely upset when I found similar products for 1/2 the price.

After a little price investigating I went back to the store and approached a sales clerk. I asked why the price was so much different but they couldn't tell me. They attempted to talk me in circles and intimidate me into not returning the overpriced product.

In the end I returned the product and purchased it from another retailer locally who didn't over charge me.
