Down in SoCal I've seen aros go from $30-$60. If you want the cheapest price, I suggest looking in your closest Chinatown. Asian fish stores have tons and are usually the cheapest when it comes to Aro's. I had to get my 6 in silver aro for 50 bucks. My first silver though was 40 bucks at 4 inches. Then while visiting a few friends in Los Angeles I stopped by chinatown to check out the fish stores and they had 6-8 in aros for 30 bucks. I'm assuming the smaller ones are even cheaper, but they didn't have any left atm.
