EDIT: Today's supply are gone, but they have 2500 freebies each day. Check back tomorrow.
I posted thisoffer in August, but turns out it's still available. I guess Invisible Glass is trying to be all passive aggressive and tell us something. Look, we're busy people, we don't have time to clean our windows every day. I've got to find freebies, take naps, answer emails, take second naps, talk in fake foreign accents while on the phone, fake naps to avoid my landlord, and then maybe squeeze in a meal or two. It's exhausting work. I need a nap just thinking about it.
[thanks for the reminder, Dan!]
