good advice, I wish to expand on it with my experience:
It doesn't matter if the clients are complaining, as long as they are buying.
It's customers' job to complain about something - usually the price - and if the price is the only thing they are complaining about, you're probably doing great :-) If nobody's complaining about the price, it is usually a sign you're selling yourself too cheap.
I always look at how the customer is actually behaving, not what he is saying. If they stop buying, then change something - not before.
