Motors vary in price from exporting country. The cheapest Motoros come from Peru they cost 10-15 dollars each and are usually packed 4 per box which lands them in USA around 20-25 dollars each. These are usually sold wholesale to the stores for 45-65 each and are retailed for 100-150 each. Colombia is where Marble Motoros originate from they are prices at roughly 60-75 dollars each and packed 1 or 2 per box so that lands them in USA anywhere from 90-125 ish per ray these are usually not imported by wholesalers so they are usually not found in pet stores. The people importing these usually double the price depending on how nice the pattern is. A MM should cost anywhere from 175-250 anymore than that is more than the standard type markup. A regular motoro from colombia cost around 30 dollars and some of these come in as MM as well since some exporters dont seperate them and mark up price along with the name. All in all the price difference between a motoro and a marbled motoro from Colombia is only an additional 30 dollars to the importer.
