Do You Buy Knitting Grab Bags?

Every now and then you'll come across a yarn company or knitting store, online or off, selling knitting grab bags, usually a collection of yarns of a similar weight or from the same manufacturer that are sold at a discount. They're often overstocks or closeouts, and the catch is that you don't get to know or see what you're buying until after the sale is made.

I really like grab bags (and usually get one every time I buy from Patternworks). Getting them is like Christmas (except no one buys me yarn for Christmas, no matter how much I'd like them to) and it's really inspiring to figure out what to do with just a ball or two or a two of a particular yarn (you'll see some of the fruits of my latest grab bag later this week.)

Do you like grab bags? Have you ever gotten one and just loved all the yarn that was inside? Or do you feel ripped off when you buy one and the yarn is all strange textures and colors? Let me know by answering this week's poll.
