As everyone knows, I've been anticipating a free cycle promo from a new source. The tracking showed it was out for delivery in my neck of the woods Monday morning, but Monday evening it showed returned to sender due to undeliverable address. I checked the email I sent to the source to ensure I didn't make a mistake. There was no mistake, & source says they just copied & pasted the address. So, my question is this, has any else had this experience & what might be the cause?
