Noticed last week when I was at Walmart that the 2 pack of Mr. Clean erasers was down to $2 so I used the $2wub2 and stocked up. Went back today and they had more so I bought more. Also noticed that all the new erasers come in a 4 pack now and they don't carry 2 packs. Maybe check it out cause all the new ones are near $5 a pack. :(
