Coke zero

Today I go into the store (GR2), and what do I see? Coca Cola Zero. Not just one bottle but a flat, who brought that in? I thought it was a generous employee who decided to treat the rest of the staff. There's a bunch of bottles in the fridge, free pens, and coupons for free 12 packs. What does it mean? Are we being marketed to? Are we a test market? Are we guinea pigs? Are we taste makers? It's probably all of that. Viral marketing of some sort is going on. I hate it. I took some some bottles, and took a taste test. Just like I thought, soda with shitty aftertaste. But regardless, it's free and I'm thirtsy - and sometimes all that beats being a guinea pig.
