Their ARE occasionally descrepancies like the above example where their is a mispricing. So in theory if you bought enough you could profit even after brokerage. Maybe the expiry os soon?
One thing to remember, it can take around 2weeks from buying the option, filling in form, sending/paying and recieving new shares in your account for sale. The sp may fall from 3.8c down to 3.5c in that time or lower.
