How to let the user enter the price for particular product in Commerce Kickstart? I have installed Commerce Kickstart (version 7.x-2.25).

I have to set the price as 100 Rs. At the same time user will enter an amount above 100rs.

Is there any option for the user to enter the price and go to cart and checkout page?
I guess you're looking for Auction


  An auction is a process of buying and selling goods or services by
  offering them up for bid, taking bids, and then selling the item to
  the highest bidder.
