For the record, I am a subscriber to Wine Searcher, and while I can attest to the value of the information they provide for many markets, I can also attest that their reliability with information from smaller markets such as Argentina can (and most of the time is) be very inaccurate. The same can be said for the large markets such as the USA, but specifically for wines from places like Argentina (ie. info on Argentine Wines from US based merchants is also quite inaccurate/outdated, etc.).

I deal with these issues on almost a daily basis, as a large portion of my US based clientele uses Wine Searcher. Their experience, which they share with me on a constant basis, shows that the information available online for US based merchants related to Argentine labels is most of the time outdated and inaccurate. This means that many times a Merchant will list a certain label, and when this Merchant is contacted.... turns out the wine is no longer available, or the vintages information is wrong, or that the listed price is outdated, or the bottle format is other than what is listed, etc. etc.... or even that the actual label/brand and/or grape variety is different. This situation is confirmed by many of my contacts ITB throughout the US. Database maintenance is not free... so merchants and vendors concentrate on the stuff that moves the most.

Bottom line... I think that Wine Searcher is a great tool and can/should be taken as a valid reference, but for Argentine Wines make sure to double & cross check the information before rapidly jumping to conclusions.
