where to buy granite worktops ?

I wonder where would be the best place to buy new granite worktops.
Probably from a place that is selling cheap granite worktops or maybe quartz worktops.
How can they make a granite worktop inexpensive ?
1) Low overheads means less bureaucracy -Watch out for too many people int he showrooms
2)Quality of materials used- do the granite fabricator buy cheap 3rd grade slabs from China / no offence OR from a renown source or granite supplier
3)Can you see the slabs before you buy the worktops
4) Are they helpful and answering any questions you might have all after all granite worktops are well priced but be honest are not cheap
5)Don’t bother really with all the prizes and medals or smokes screens they present you with
Keep it simple.
