This is kid of weird. They list a lot of different products that are geared towards caring for the elderly, but also includes Huggies diapers and Ensure. You buy a minimum of 5 products and can mail in for a rebate (most items are $1). Unlimited number of submissions, so if you're constantly buying some of these items it's like a perpetual rebate. Expires 1/31/09. Needs original receipts, but no UPC's.

Other odd thing is that for the diapers, it's only valid on the Jumbo packs. But hey, if I find a good enough deal, this makes it better.
