I got my red ones (red plate, white 'P') from BigW. Lasted about a month b4 I got pulled over and warned about them coz technically I'm not allowed to use them coz I'm on the older style P's. But yeah by the time I got warned about them they were always falling down anyways.
When I first tried the sticky ones I ended up throwing them away coz they didn't work....but when I decided to try them a 2nd time when I bought some about a year l8r, I realised there was a plastic film over the plate which had to be removed....last time I didn't know and that's why it never stuck haha.
