Basically it is like eBay where people are able to register and then bid on items. All the items are horse items.
The client is thinking that it is $3. I suggest that it is offered as a free app and then if they want to either place a bid or list an item, then they need to upgrade to the paid version which would be $2.99. There would be a time limit and an opening value. Then when the time finishes, the winning bidder is notified and so is the seller.
