OK, so you edited out the section I quoted.
It also isn't a just a case of " issues shouldnt get as far as forums", sometimes it is the easiest way to communicate with the Scan guys. Especially for existing forum members. for example it is by far the easiest way for me to ask pre-sales questions or raise issues as I am here anyway. No-one is forcing you to use the forums, they are just another way to communicate with the Scan chaps.
As for your "postage" example, if you are comparing to other sites are you also taking Next Day Courier delivery into account? This is the standard Scan delivery option. I'm sure some people would really like a standard free delivery option that took longer, but it is obviously Scans decision not to have this. There are very good business reasons for delivery structured the way it is.
If the cost of an item, plus the £8.21 Next Day delivery is too much for you, then order it else where.
