Exhibitions and shows such as PC Show, Travel Fair, etc... are well attended.
Not everyone thinks alike.
So to each his or her own.
Sim Lim Square does have equal or better deals than PC Show, provided you know how to find them.
There is regular news that some newbie got cheated again at SLS buying stuff at grossly inflated prices from dishonest salesmen.
The PC Show exhibitors or stall holders pay steep rentals to the show organiser and have to either break even or make a profit.
PC Show in SG nowadays do not function as a peep into the future where top manufacturers showcase their latest gadgets or indicate their future tech R&D. Maybe in America they still do. Nowadays, PC Show is a big pasar malam from noon to late evening.
But Singaporeans got few places to go on weekends where attendance is free. It is the school holidays. So the PC Show becomes a family outing for many.
