The estimated delivery times depend on the typology of the product purchased and on its availability. Take jammers for example: as for every other spy-tech device, it will take 1-2 business days for the product to be shipped, from the date of payment.
It is a whole different situation when dealing with other self-defense devices: 48 hours if available. Otherwise, it will take almost 12 days if unavailable.
Furthermore, it is an entirely different story when dealing with Encrypted Systems, which will be managed within a few hours. It is implied that all of the above has to be preceded by the payment, therefore the chosen payment method can affect the delivery date, too.
