I haven't tried it, but I like other Purex products, so I'll look for it at the store next time.
As far as what I normally use, I usually just buy whatever's on sale and/or what I have a coupon for. If you watch for deals, you can get name brand laundry detergent really cheap ... often $1.50 or less. Sometimes I make my own by using Fels Naptha soap, borax, and washing soda.
I actually don't care for Tide. It costs too much (even on sale), and it doesn't agree with my nose.
