No idea what the o is for on their site. I'm ordering the same stuff (minus the o) for 184.99 from
Newegg.
Don't know if you have purchased from SuperBiiz before or not. I noticed they had a couple lower priced items. After doing the Google thing just decided way too many bad reviews (long shipping, CC disputes, etc) and not BBB accredited. I'm sticking with Newegg and Amazon myself. The extra couple bucks buys me piece of mind is all ;)
