They come up with new colors that kind of flop, and obsolete some models.
You can also shop home goods stores, and their outlet stores.
Hints:
Staub has regular sales as well, and they all seem to have dark enamel coating that hides and "patina" loved by some purists.
LeC uses a dark enamel on some pieces, like the skillet.
Find online or retail at WS and SLT, perhaps others.
And there are much cheaper clones of unknown long term durability. Cuisinart has many, as do Lodge and others. You can get 4 of them for one LeC. I found a nice Chantal 5 quart for reasonable. Alas, that's the biggest I can actually use for one, when I make Mom's meat gravy recipe (uses a large 28 ounce can of tomatoes, 6 meals ) and keeps/freezes.
LeCreuset sells some cleaner that seems to have changed chemistry. Any one that has mild acid seems to work well. As always, no thermal shock, and use plastic/wood utensils.
Lifetime warranty unless you tell them that movers damaged the item.
AllClad and Calphalon recommended for heavy/restaurant use. Cuisinart mostly uses a metal disk base, but has some tri-ply, if that matters.
