Costco or Kirkland brand Eggbeaters (forget what they're called). They taste better and cost about 1/3 of what the brand name Eggbeaters cost.
Costco or Kirkland brand liquid fabric softener. It smells and feels like Downy, but again, about a third of the cost.
Costco or Kirkland brand fabric softener sheets. Do a great job, smell great and about the 1/3 the cost of other brands.
Costco or Kirkland brand dish washer soap, a knock off of Cascade. Two huge boxes for the price of a medium size Cascade box at the supermarket.
Store brand Cherrios. One you put skim milk and a banana on the cereal, it all tastes the same.
Store brand coffee creamer, light. It tastes better than Cremora or other coffee creamer things.
The Dollar Tree dollar store for tea light candles ... 20 for a buck compared to Yankee Candle at 12 for $4.95. They last almost as long, maybe an hour less. But that's one of my favorite buys!
That's all I can think of right now.

I always buy my sterling silver jewelry from QVC, and I don't do the label thing for clothes, shoes (except Tevas), handbags, makeup etc. so I can't help there!

Just buy where ever, whatever I like, but I do like Smash Box cosmetics a lot.
