.50c ? that's crazy for that kind of service, especially when Apple is actually doing the delivery.

Usually the service adds bells and whistles like geo-location targeting, segmentation, scheduled delivery, and other things.

Urban Airship seems to be targeting larger customers these days though, and their pricing reflects it.

That's only the pricing for small-time users.

plus apple doesn't guarantee the delivery as well

Push notification services never guarantee delivery.
