you should check the actual limitations and coverage dollar amounts. some items are different. medical evacuation for one company may be $25,000 and for another $50,000, medical coverage could be similar as well, $10,000 for one $25,000 for another. those amounts could be what changes. They may also give you quotes based on your vacation cost, let's say $3,800. If they classify costs as being $3,000 - $4,000 as a category for one company, but $3,500 - $5,000 for another company that would raise your rates. Factors like this could contribute and the possibility one just charges more. I am looking into Travelex for our trip in January.
