Jon have you looked at KMart and Stop and Shop? They sell the smaller boxes of Original Scent Tide w/Bleach. CVS once in awhile has it as well and on sale too. Target I am finding carried the larger boxes of Tide w/Bleach but in the Clean Breeze scent. Shaws also carries Tide w/Bleach powder. I never have a problem finding the stuff. The Tide w/Bleach Advanced that they sell at Costco is hard to find. I went last week since I had a coupon for $2.50 off but they didnt have any. That was the one on Rt1 in Danvers.
I know for myself I would love some Drive from Down Under. When I saw the pics I would be in heaven there and even the Cold Power. I wish they sold that here in the States.
I also noticed that they had the tubes of super concentrate softener. I found something like that in Canada for Fleecy where one uses a gallon jug and when one runs out of the gallon you use that concentrate and then add water. Kinda neat and a good idea.
As another posted stated, is an activated oxygen bleach for soaking, and santising cloth diapers. Many add it to wash loads as well for whitening and sanitising.
If one wants chlorine bleach for the nursery, there are Milton tablets.
