Thank you for all your posts. I have already checked on google and found that tickets can be purchase on the event site and can be purchase also on agent site. So, my posts were to find the appropriate sites where I can purchase smoothly as I have found agent sites are taking lower than original price and I was confused how it can be possible? And, I have posted similar posts due to not every one is expert on all events. So, who is expert on particular event can answer on specific post like you did not Siam Ocean World. Thank you for your help and hope you have understood my objectives.
