Right, I had the same problem.
Last night when I was trying to place an order for one of the Thursday promos the "Free Glass Toy" could not be added to my cart.
It did briefly come back up this morning around 10:00am EST, so I was able to add a free Hearts Wand to my cart. Unfortunately, the prices from the Thursday promos had expired. Arrrgh! So, my wife ordered something from the Friday promo instead. She made out like a Bandit.
The Free Glass Toy promo was removed from the Eden home page a short time later. And...yes, it was removed before the 2pm time stated on the promo. I've noticed this happening before, so I try to jump on promos that I like.
