caution there is NO attachment all info is standing here under:
How it must work:
The auctionsite works NOT like regular auction where it the Highest bid wins, but we want auction where the Lowest bid wins, but caution: the lowest UNIQUE bid.
So winner has that bid that is the lowest
but also the winner must be the only person who bid that amount on end of bidperiod (so unique)
if auction close at 10 PM and you have the lowest bid and you are the only one with this bid, you will win the auction at have to pay the price you bidded.
Bidding must go via SMS (short message service), so bidder send his price in cents to shortcode (eg 4488) for SMS, and automatically he get SMS back, bidder get SMS back from Admin with info if he is lowest Unique bidder yes or no. if not bidder can decide to bid again.
Example of SMS bidding:
SMS; PDA>amount in cents> to 4488
