HELPPPP! PLEASEE! Online shopping?

Hey I live in Guayaquil, Ecuador and down here the malls don't have all these popular american stores such as Abercrombie and Aeropostle and etc. Although my parents allow me to shop online but the shipping rates are ridiculous, so Im hoping someone knows a website or maybe a certain credit card I would have to use in order to avoid the overpriced shipping rates.Thank you in Advance =)
