Quality super, but overpriced

For the price:

Goods as Amazon SUBSCRIPTION until the end of 2011 just yet reasonably priced.
Since the beginning of 2012, the savings SUBSCRIPTION was terminated and changed the packaging unit of 4 brushes in only 3 brushes from Braun / Oral B. Since then, the savings SUBSCRIPTION is available again, but much too expensive.
I would love to change our electric toothbrushes to Philips or on a no-name product, because I do not find the pricing reasonable !!!
