Marking Unmarked Graves

I stumbled upon a company that makes ordering stones for unmarked graves simple and very affordable. I haven't used their service yet but it sounds very interesting. Mark Every Grave allows you to order small granite headstones (6" x 9") starting at $25.99 for 6" x 9" x 1/2" stones up to 24" x 12" x 1/2" for $250. You can select an image to have engraved in addition to names and dates for a small amount more. There is also an option for a custom image. Their web site notes that shipping is free.
