ComFi.com calling cards look like they offer great rates, so I was definitely going to try them. They advertise their low rate to call Sweden at just under one penny. This card looks good on the surface but it has more fees than a Hospital.
Besides an outrageous weekly fee of nearly one dollar, what is this: Service Taxes & Surcharges 25% + 10% on calls over 1? What does this even mean? So they want to charge me 35% on a ten minute call? So now the rate is well over one penny.
IMHO there are many better options. Watch out for sucky characters like Comfi.com.
