Ordered from MarcoRocks, confusion about exactly what I ordered.

So I just ordered 4 of these from MarcoRocks http://ift.tt/1opDHQY

But I am a little unsure of what exactly I should be expecting. Should I be expecting 4 rocks? Or 4 of the packages that are pictured? Anyone that could provide some insight it would be appreciated, just curious how many rocks I should be expecting.
