u pay through the nose unless u know someone

all my PC rigs bought from tradepac, i don't know them but i get the cheapest price.
But to know someone you gotta be customer first.
Back in those days, i pretty much shopped based on price
Initially it was cheapest price first
Then i realised it was real stupid coz price of pc components are extremely competitive
Shops can are wiling to give $1 discount just to close the deal.
But the clincher is in the aftersales service
If something goes wrong, cheapo hops immediately point you to distro
Distro means half day leave and $30 to and fro on avg
MSRP shops usually make the problem theirs.
So after a while
Stuck to the big shops and started buying PCs from them
This paid off for me now as the aftersales service is worth more than the $10 savings between the cheapo shops and MSRP shops coz what you save upfront, may not cover the hidden costs you need to spend if something goes wrong.
Hidden cost is not just transport, but can be the upsell tactics to get something to fix an issue when that proposed something has totally no relation to the issue @ hand.
So to original threadstarter
Sim Lim Square is usually meant for System Integrators or wannabe system integrators
Everyshop can do everything but each shop specialises in some things.
Think of them as the contractor, not the ID
Go into each of the shops and see for yourself which shop gives yout good vibes when you step in.
Shops that want to move stuff quickly means less customer interaction quicker sales to close
Shops that focus on service are patient enough to explain stuff without rushing.
There are many shops recommended by the forumners here so they make good starting points.
