1/Same distillery, three years apart: Glenfiddich's 15 against its 18. Both are sitting at the bottom of their own recent tickets this Thursday. $125 for the 15, $170 for the 18, plain shelf at Dan Murphy's, no member deal on either.
2/Buy the two together and it's $294.80 today. What's interesting isn't the total — it's that both legs hit their own floor in the same week. That doesn't line up often, and it's a short window, so read it as timing rather than a verdict.
3/The jump to the 18 is $45. That's about the usual gap between these two, so the older bottle isn't unusually dear right now, nor a steal. You're paying roughly its normal age premium, just from a lower base.
4/So it's the plain question with the markup stripped out: are Glenfiddich's extra three years worth $45 to you today, or does the 15 already do the job? Both Dan Murphy's this week. Tell me where you'd stop.

Two shelf tickets and each bottle's own-history position only; no CE 360 bands, no cross-read CEARP, no Welch t-test quoted (the light form excludes them). Both prices shelf basis, neither on a member offer this week. Both 700mL, same distillery. This is an age-ladder timing note, not a similarity claim: the VSM profile model ranks the two 5th-closest (same house), the value model 26th (rank_diff -21), so it reads them as one distillery's step-up, both at their own floor, not as interchangeable.
