Fixed Price In Product Page but default price converted in the cart

Hi,

My website sells tour packages to brazilian costumers, buying in brazilan IPs. My default currency in the website is US dolars, because I receive in Brazilian Reais (BRL) but pay my suppliers in Us dolars (USD), so to don’t lose money on the exchange rate variation I set the prces in US and they are converted by Currency switcher to Reais when the pugin find the location of the IP in Brazil.

For the tours that are operated inside Brazil, I use the fixed price in reais, as I don’t have echange rate variation because my suppliers are in brazil, so i sell in the fixed price in BRL and pay my suppliers in brazil in bRL.

My problem, is that the product page show the fixed price when the client is shopping, but when they add the product to the cart, in the cart it appears the Default price in USD converted by the day’s exchange rate.

For example.

i have a product that coasts BRL 1560 (on the settings, I setted USd dolars as default value and added the fixed price in BRL of BrL 1560.

On the product page the client sees the BRL 1560, but when he add to the cart, it changes the price for BRL 1737, because the sistem converted the default value of USD 330 by the exchange rate of the day.

i need a help for the fixed price to appear in the cart, as it appears in the product page.
