Beg for a ticket of commodities fair

I am a big fan of laser torch flashlight. It is pretty good news for me that there will be a blue light laser pointer fair holding in my city at this weekend,

In the appointed time, various kinds of Blue Beam Laser Pointer would show their figures at that big day, it is stated that the up-to-date 100mW blue Laser produced by Norway would be spot, and benefit from promotion activity cooperated whit 5 large scale laser pointer company, the consumers could buy blue laser at a very discount prize, they even regard it as “the most cheap blue laser pointer in the history”. Fabulous, isn’t it? That is why a buyer with the ticket is allowed to get into it.

I would like to buy high power laser form the coming commodities fair, I am definitely quite sure that it is not only a powerful laser but also the Cheap Blue Laser. But a ticket is difficult to ask, who would like to give me a ticket here? I will be appreciated.
