I am seeing this reported on a couple of sites: The J&J First Aid kits are working on the ECB deal this week: Buy two J&J products get 2 ECBs back. These kits regularly sell for $0.99 each. You can get them free after ECBs with this deal. You can find these kits by the travel section in your store.
Another hidden deal I am seeing reported too is on the 10ct box of regular and super CVS brand of Tampons. Buy one box for $1.89 and earn $1.89 back. Free after ECBs!! This deal is not advertised in your sales circular but it is reportedly tagged in stores. Limit is 1 per card.
Happy savings!
