I know that there are three vias, blind/buried vias and through hole vias. But of the products I see will use through hole vias rather than blind and buried vias, why?

The deciding poingt is Cost.. For example,I want to get a quote with 60*80MM 4 layer PCB design. I get a quote for 22K USD for 20 pieces, I naturally objected.They said is because it has buried vias. Later, I changed the design sent the gerbers back, price was 150$ in 5 working days. Unless you have BGA package, don't use any via other than through hole.

Blind and buried vias will cost more on a multi-layer board. Because their high cost,they are only used on high-density, high-performance systems.
