What is special about other levels?, page-5

I think I understand the service being offered @stocking, it is indeed the value of the service I'm questioning. The examples you have supplied Chris do seem reasonable enough. That said, if I spend some time looking for camper van rentals in the NT and don't have my security settings high enough I will find adds for them turning up on my browser.  This obviously works to some extent or they wouldn't do it, but if I got a message on my mobile telling me I had been to such a shop 4 times in the last week I would turn off my location settings and not go back, but hey, maybe that's just me, lol.
