There are so many PHP scripts that are available, many of which are developed by casual, individual programmers.  They have their websites to sell their PHP software packages.  Many of them don't survive for a long time.

One thing that disturbes us about many of these casual PHP programmers is that they don't state their office locations at their websites.  Honestly, we don't know why.  Just as when we purchase computer software programs, we try not to buy anything from these people with no addresses.  The worst one we have seen is a software developer from India who refuses to even post his contact e-mail address.  And the only way of asking him questions was to post them at his website forums.  So we decided not to buy anything from him.

There's another disturbing fact about these casual software developers.  Many of them are committed to answering every question from potential customers.  But once you pay and install software, some of them don't bother to answer any more questions from existing customers.

Anyway, we purchase PHP software programs once in a while.  And we decided to write extensive reviews on them.  Hopefully, you can make a better decision before buying it.  Again, if you can, don't buy anything from those who do not state their office locations.
