@Kaycee: thx for your expert insight...
but for fairness factor, they should consider the lot queue system (those register early in their database will have earlier chance in the lot queue, than those register afterward).
It would not be fair to those 3rd-clickers that kept persistent in trying each release, if Stockland Elara is easily giving lot spot chance to the 1st-clicker, just because of their fast-hand (milliseconds) and general survey (people's preference can change at anytime)..
Hope someone can discuss this topic to the sales person, i'll mention it when i had a chance to drop-by.
