We are not ready to call this price.
We check at least every 12 hours and hold a day-by-day record of what this cost — 3 days of it so far. Calling a price high or low needs 7 of those days and at least one change, because a range needs two prices: this one has not moved since we started watching. If it is still $27.99 on October 18, this box will say so — a price that has held for 10 days is an answer too.
LEGO set 71854, 364 pieces by Rebrickable’s count: 7.7¢ a piece at today’s $27.99, 20% below LEGO’s list price of $34.99. Every theme, per piece
