I have been running my own oscommerce store now for a couple of years and day after day I found myself thinking 'It would be great if I could do this' and 'I wish I knew how to do that'. When I found 'Deep Inside osCommerce' by Monika Mathé I was like a child in a sweet shop!
My wife thought that I was mad when I said that she had to drive home, I had to start reading it.
As soon as I got home I emailed the publisher for copies of the source code (to save my little fingers all that typing). The first recipe that really jumped out at me was in Chapter 2 'Create Separate Boxes for Each Top Category', I had toyed with solutions for this in the past with little success. This recipe was perfect for the job and was up an running in 10 minutes. I was amazed at how such a simple solution could provide great results.
Now I must say I am not the type of person who reads a book from cover to cover and then starts experimenting, I just get in and get my hands dirty!
One of the biggest questions I always get from my customers is 'How do I remove products from my shopping cart?' and I have to explain that you need to check the tick box and then click the update button, not anymore. Monika's recipe for a one click solution has saved me many man hours of replying to emails.
I always had a grumble whenever I had to change any of my stores' configuration values, all those options are not helped by the oscommerce default sort order and also the links were never highlighted (which you think they would be). In this book there is a recipe for highlighting and seperating the links into a more eye friendly display, grouping them by logic or even alphabetically.
As part of our future expansion plans we intend to start importing directly from China, Monika's recipe for adding an additional currency when entering a new product was just what we are looking for and this is already now a feature of our shop which will be put to very good use.
To summarise, this book is well worth the money, it will save you quite a few pounds in developer fees. It is neat, tidy and easy to follow and further more very very tasty!
