Yep, some of us remember a nationwide chain store slogan that was used everywhere and for what seemed like forever. I don't know when or even if the 99 Cents Only Store discontinued it - I stopped shopping at my local one, after it got way too crowded from Opening to Close, and was stocking even crappier stuff than usual. Wasn't keeping track, but pretty sure the slogan was around in the mid-2000s.
