Refine item with model number
Like most shopping assistants, This one is bad about respecting the details of the Item wanted. Example, go to Samsung and look up SSD drives. Chose the 850 EVO 500GB drive. Hit the heart to save the product. You then get told you can get the product for $85, but when you click on the link, it's for the 120GB version of the drive. There needs to be a way to refine the saved item by giving it the exact model number you are looking for. This way you can get prices on the right item. It would be ok for it to also list similar items in a separate list.
