The company that your link leads to - MacNeil Automotive Products - is an accredited business with the Better Business Bureau, so it's a legitimate and probably reliable business.
I got some very nice floor mats from rockauto.com - ACC Cut Pile for $46 for both fronts. They are cut to fit very well, but they didn't have the medium gray to match my truck so I got the charcoal. They're too dark - if I'd seen them first I probably would have kept looking, but they are very nice quality, especially for the price. I'm not sure if rockauto would ship to Costa Rica, but it's worth asking them. They carry other mats, too.
