It all depends on what a user needs e.g. if you are building a pc, there are a number of suppliers.
If buying a second hand pc, shops in Aberdeen like "Cash Converters" can give a good deal (Caveat Emptor is somewhat applicable)
If buying a new or refurbished pc, there are a number of companies. I bought my laptop being used now from Laptops Direct.
I never select a specific site but do research to see where I get best deal (but only via reputable dealers).
For same reason, I might use Amazon but would never buy from ebay (ok might take a risk if cheap enough).
