Breast pump as a shower gift

On one of my registries, I registered for a breast pump. Not that I want someone to get me a breast pump mind you. Baby-r-Us and Target will allow you to buy any products that haven't been bought as gifts at a 10% discount after the due date. So I have some high end products (pack 'n play) and some odd ones (breast pump) that I absolutely do not expect people to get but that I can take advantage of the discount later. To my surprise, someone bought the breast pump when I checked the registry today (it's only 9 days til my baby shower). I'm grateful, but slightly disturbed.
