Mark1406 ~ the GIN is automatically disabled when a bidder bids 50% of the Gin since you set the starting bid at 600,000 and the gin at only 1,100,000 the minute I bid 600,000 the GIN was disabled by my bid automatically :) Your GIN should always be more than 50% of your start bid otherwise the GIN will be disabled automatically.
If I set a gin at 1,000,000 and my start bid is 500,000 the minute someone bids that 500,000 the gin will be disabled :)
