Cool! I had codex have a go at calculating "effective price" on a few items, that prices in the assembly labor, and then also calculates the delta between price and effective price. Obviously very depended on how you value your time, but here are some items at $30/hour:

BRIMNES storage bed + headboard, Queen $549 + 320 min labor = $709 (delta: +$160 / +29%)

HEMNES 8-drawer dresser $380 + 236 min labor = $498 (delta: +$118 / +31%)

STORKLINTA 6-drawer dresser $250 + 224 min labor = $362 (delta: +$112 / +45%)

SLÄKT storage bed, Twin $450 + 212 min labor = $556 (delta: +$106 / +24%)

BRIMNES 3-door wardrobe $250 + 189 min labor = $344.50 (delta: +$94.50 / +38%)

ALEX drawer unit: $95 + 96 min labor = $143 (delta: +$48 / +51%)

BRIMNES cabinet with doors: $99 + 75 min labor = $136.50 (delta: +$37.50 / +38%)

KALLAX 2x4 shelf unit: $65 + 39 min labor = $84.50 (delta: +$19.50 / +30%)

Formula: effective price = sticker price + (estimated assembly minutes / 60 * hourly value of time).

I was surprised by how similar the % diff is across the board.

If an ALEX drawer unit takes them over an hour and a half to build, IMHO they're doing something wrong. Many others on that list seem suspiciously high (the BRIMNES comes to mind). Curious how it came up with those values.

		Sloppily. I doubt there's much information on the web that says "mounting a BRIMNES takes five hours, twenty minutes." So what's an LLM to do? Produce any number in the semantic vicinity of the sequence "mounting"+ "BRIMNES" + "takes". So that can be anything that says "building an IKEA closet cost me" or "climbing mount Bayimes takes on average" or perhaps even "building a mountain bayke [spelling error] can take". And then from all sentences that get close to that point, it takes the next likely token. So 320 minutes it is.
