I visited a Le Creuset outlet store this weekend for the first time, and was surprised that given that on this board people often recommend the outlet for good prices, the prices didn't seem great to me. Now, that may be b/c I live in NYC, and places like Broadway Panhandler generally have very good discounts. The only deals I found were on a table with things that were drastically reduced - four round ramekins for $2.99, a huge oval ceramic casserole w/ lid for $39.99 and a small squarish casserole w/ lid for $14.99. Other than that (and the seconds on the enamel ware, which were about 15% off the discounted price for first quality), the prices were pretty much what I kind find here ($101, off from $150, for a enamel cast iron pate terrine). The Riedel glasses were actually more expensive than at William Sonoma - I had just looked at them there last week, and at Le Creuset, they were a couple of dollars more per glass. (BTW - The Brown Derby is a great place to buy Riedel at a discount.)
So, I had fun browsing and am happy with my purchases, but would urge buyers not to assume that the outlet has the best prices.
