Seems to be a common thing these days: spelling errors, grammatical mistakes, and so on. And we tend to accept it.
This one is an error on a car sticker; a promotion where you can win a prize. But, and its a big but, using a catch-phrase like "Your With The Best" can backfire pretty quickly. The best? Not their marketing department that proof read the sticker before printing.
To top it all off, the competition is outlined on the reverse "Over the next month...blah blah...". But there is no date, no month, no indication whatsoever of when the competition is running.
So one error, ok, move on. Two...wouldn't want to be the proof reader!
