Before you buy
- ✓Search by the set number on the box (five digits, like 75447): every store prints it, and it is how this page matches the same set across stores.
- ✓LEGO's own recommended price is the ceiling, not the norm: toy stores often run 20–40% off popular sets, and big sets drop most around Black Friday and Boxing Day.
- ✓Sets retire after two or three years and then rise in price, so a set you want that has been on shelves a while is worth buying before it goes.
