Autobarn review: Flier advertising products you don't have

I received a flier in my letterbox on 27/1. I saw an advertisement for car stereo's & noticed one I liked. I travelled 30 kms to the nearest store, only to find they don't have it, or anything like it. I asked if they had sold out already, but was told, no, they just haven't had any new stock for 6 months. I know from experience it's common for stores to not have advertised items/specials in this country, it's happened many times before. However, I drove 30 ks, & wasted an hour of my time, to find the store had about 3 stereo's left, none suitable for me, so I'm a little jacked off. I'm considering taking this further, because I'm over this kind of thing. It's false advertising.
