Ok... I know it's not very organized, but this is just the first cut.
These are random pieces of articles I wrote to my friends or published on websites about product review, shopping tips, and merchant/service provider experience. Some of them only applies to local areas, but some are good for the general public. I am not a professional, but personal experience is sometimes more relevant to you, don't you think?
Again, more will be added as this site develops...
