[lombiolove]

Hello everyone, (especially if you are from Miami or know the place!) A friend of mine is getting a new PC, his uncle is from Miami (they are going to be on Orlando for most of the time) and he is going to buy the stuff and send it back to his home country (Argentina), what i need some help with is if you guys know any big pc stores that sell parts like microcenter or such that have decent prices and availability of items so i can recomend him to get there with a list of possible parts to buy quickly and safely.

Extra points if anyone can provide urls so we can check them out beforehand! Any recomendations or advice are appreciated! :)
