Where to buy landscaping rocks

Looking for landscaping rocks (about the size of a brick) to edge with.  Does anyone know where I can get those?  How much do you think they'd be?  I probably need about 30.

try ZO LANDSCAPING on Newark way, Orange Garden Supply off of Scotland road in Orange, or Maplewood garden supply just past the Home Depot heading towards Morris ave. there's also a stone place on 22 west in Springfield.

The place in Springfield is Boychuk at 360 US22. They have an excellent selection and they deliver to Maplewood.

Thanks!
