You can't buy Teflon-coated cookware anymore.
We have $4,000 worth of All-Clad original stainless (not the M2), and that's after the sweet deal Macy's usually has once a year during their twice-a-year 25% Friends and Family sale (so you get 25% off, and if you buy a lot of All-Clad you get a bunch of other All-Clad crap for free). Yes, we have tons of duplicates but we started out with one or two of everything. I have a couple pieces of their copper stuff but to be honest they're not worth it as far as I can tell (I'm not a professional). It takes up a lot of cupboard space but it's worth having a lot because you have no emergencies when cooking where you are struggling to get a piece washed while cooking. I always thought the butter warmer pot thing was stupid until I used it. It's a bit to stomach $100+ for a frypan, saucepan, or sautepan... until you realize it will outlive you even if you abuse it. The only thing you can't do with it is leave it sitting in water where the lip is in the water. If you do, it will corrode the aluminum between the two pieces of stainless due to galvanic corrosion. It is dishwasher safe though, and it does work on an induction cooktop.
Only the original All-Clad or the copper items are worth buying. The rest of it will disappoint you for the money. A good way to tell if you're going to be disappointed is if it doesn't have a serial number on it.
All-Clad's nonstick stuff isn't all that great for the price. I'd rather use French (impossible to find anymore) T-Fal or their above-average Chinese frypans if I need nonstick and this is the one we use currently:

It's difficult to make eggs or hashbrowns or a lot of other things with a cheap aluminum or stainless pan if you're on an electric range... unless you use a lot of real butter or some kind of oil. So, it does change your cooking habits. A higher quality piece of equipment, like All-Clad, makes it a lot easier to cook without nonstick on an electric range.
Once in a while All-Clad has a sell-off of their overstock/returns/blems:

Years ago they used to do it once a year. I think they're doing it quarterly now.
