Multiple Price for same product in commerce kickstart? I have installed Commerce kickstart. I have add the products. 
Now my client asked Same product have two different prices. User will choose the price and pay it.

I am trying Commerce Donate module also.This module price for every product. 

I need to change the price value for every product.
Might as well jump all in using Commerce Customizable Products and use this screencast to walk yourself through adding a line item type and a field to set the price.
