Dang they sell quick.. They just got some in last week.. These test kits are made in Holland so there shipping is not up to par with the Demand.. I'd check around with other online sellers.. But usually when one runs out they all are out.. Yes they are very popular.. I would say that they usually have them in stock within a weeks time frame.. I would definetly wait until they are.. Maybe you can get a new batch of the new testing procedure and Reagents.. Supposed to make it much easier to read... But I was informed the new test would take 2-3 months to get into the US..
