Query: HighWay Robbery

I have this phone set and was looking for an extra extension phone. Why are they ripping us off for a single extension? It is better value to just replace your entire system with one that offers inexpensive extension handsets at a fraction of the price. This is a case of people taking advantage of others. No way they should be charging such a ridiculous price. I can get a brand new entire system for just another $25 that has fresh batteries in it and limitless extensions at a fraction of the cost of these thieves.
