I looked up Whirlpool part numbers & then looked up on your site. My Frig shelf & door bin were the correct ones, however the freezer wire rack was the wrong one. Since the dimensions were not listed on the item order page, I ordered one that was smaller than the one I wanted.
I placed my order on Monday & received the parts on Wednesday & Thursday. Very pleased with how quickly they were delivered.
I'm returning the wrong size & reordering the correct size. Website is very user friendly.
