I get my income in euros. I need to pay stuff in USD because I use shops which base-currency is USD such as Dealextreme. I have Visa Debit card so not the real Visa, since I am a student but have stable income streams monthly. I get the following spread-costs with my card:
- Dealextreme, 9.59%, when paying in euros USD-stuff kun euroina maksaminen ja base currency USD 
- Dealextreme, 2.06%, when paying in USD USD-stuff 
I get the current course of one euro in USD from Google.
The spread-cost, 2.06%, is huge. I would like to get it even smaller. Which credit-card does minimize the given spread-cost even more?
2. Is there any other ways to minimize the given spread-cost even more?
I did not use Paypal in buying my shoppings. I am not sure about Paypal's spread-cost, probably worser than directly with the given credit card.
