As a bidder, I want to bid for an item in an auction.

[tannerdanger]

1. The bid must be equal or greater than the minimum accepted bid for the item

• Bidder places a bid equal to the minimum acceptable
• Bidder places a bid greater than the minimum acceptable
• Bidder places a bid less than the minimum acceptable

2. No bids can be placed on or after 12:00am on the starting date of the auction (date and time is in the local time zone for the auction).

• Bidder wants to change bid the day before an auction
• Bidder wants to place bid on the auction date
• Bidder wants to place bid the day after an auction ends

3. No bidder can bid on more than a maximum number of items per auction, default of 4

• Bidder already has bids on one less than the maximum number of items per auction
• Bidder already has bids on the maximum number of items per auction

4. No bidder can bid on more than a maximum number of items for all future auctions, default of 10
   Bidder already has bids on one less than the maximum number of items for all future auctions, and there is more than one bid in past auctions.
