Before I pick a color for my free Glidden quart of paint, I'd like to go see some chips. Who sells Glidden? I've checked Ace, Walmart and Home Depot. No luck so far. Even for free I'd like to pick a color I'm really going to use. But, I'm worried that if I work too long choosing a color the offer will expire. Any idea why they would choose to send out paint rather than gift certificates? Or are they really going to send GCs? (In that case, I figure my local store, whoever they are, might let me pick a different color when I show up).
