I usually like to think that advertising doesn't have that big an effect on me. I like a clever, funny commercial (those ones are in the overwhelming minority), but as often as not I don't actually notice what it's for. I generally base my decisions on what brand to buy based on what seems like good value or what's better quality once we've tried it.
We also have an unwritten rule in our house that when a new chip flavour comes out, we buy a bag and try it. This went horribly wrong once or twice, because if there's a pack of gum or an open bag of chips on the counter, my husband shovels some into his mouth without really looking - I once told him that he could buy his own mints instead of always asking me for one of mine, but then we agreed that if he did that he would down them all at once and die in an agonizing surfeit of mintiness. So when he came across the open bag of Lay's curry chips (they were not good - the curry flavour was very unsubtle) it was very unpleasant. I said "didn't you look at the label first?" After he stopped choking and crying, he said "no, of course not! You know me - hey, free cocaine!"
But every now and then, one slips past my mental firewall. I don't even try to pretend otherwise.
I mean, wtf even is this? At first I thought, "oh, it's Pepsi's answer to Coke Zero. No, wait, it's still Coke". It's not Coke. It's not Diet Coke. It's not Coke Zero. It's a magical NEW Coke thing. It's green! That means it's healthy! Wait, no it's not. It's sweetened with natural sources! Wait, sugar is natural.
There is literally no good reason for this product to exist.
And yes, I bought six tiny cans. It tastes like slightly sweeter Coke Zero, which I don't even like. I figure Collette and I will mix it with rum while decorating her house at an absurdly early date for the Christmas party.
I am suitably chastened.
