Every calendar here was opened.

Each is computed from the record at build time, states the count it is drawn from, and is set against the median of the same season and the same kind of contents. Where the record cannot support a figure the page leaves it out rather than guessing. Dollar conversions use rough rates and are for ranking only; the shop’s own figure is always shown in its own currency.

Door price

The price on the box divided by the number of doors: the unit price of an advent calendar.

List price over doors, in the shop’s own currency. Ranked as the share of the same season’s calendars of the same kind with a cheaper door, in dollars at a rough rate, and only where at least eight carry a price.

It says nothing about what is behind the doors. A cheap door full of samples is still a cheap door.

Value multiple

What the contents come to at retail, over the price on the box. “4.6×” means the items inside would cost 4.6 times the calendar.

Contents value over list price. Every page says whose count the contents value is: the retailer’s own figure, which is every exported record, or ours where an editor has priced the items one by one.

A retailer’s valuation uses full recommended prices for items that often sell for less. Treat a brand’s multiple as its claim, and read the millilitres beside it.

Full-size share

How many of the items are the size sold on the shelf, rather than a mini, a travel size or a sample.

Full-size items over items whose size class is known, and only where at least four in five items are classed — a share drawn from three items out of forty is not a share. Where the retailer states the split but does not itemise it, that count is used and named as theirs. Beauty calendars only; a whisky calendar is twenty-four miniatures by design.

Full size is not the same as good. It is the answer to “how much of this will I still be using in February”, and nothing else.

Brands inside

How many different makers are behind the doors, and how many items are the calendar’s own brand.

Distinct makers named in the manifest. Single-brand where every named maker is the calendar’s own; otherwise the count, and the share that are own-label.

A long roll-call is the pitch of a retailer’s box and no measure of quality; a single-brand box from a house you already buy from is often the better gift.

Product inside

The millilitres the manifest states, summed — and the price per millilitre.

Only items with a metric volume are counted; the page says how many of the items that is. Beauty and drinks only.

It weights a body lotion the same as a serum. Volume is the one figure a recommended retail price cannot inflate, which is why it sits beside the value multiple; it is not a substitute for reading the list.

What’s behind the doors, by type

The items by what they are — serums, mascaras, candles — commonest first.

From the manifest’s type field. Items nobody has typed yet are counted as unlisted rather than guessed at.

“Skincare-led” describes the count, not the quality of any one item.

Carried over

How many items in this edition also appeared in the one before it.

Item names matched across the two editions, after stripping size words. A renamed product will not match, so the count can be low but never high.

Two editions with the same names can hold different sizes of the same thing.

Good deal

A door price below the median for its season and kind, and a value multiple above it. Both at once.

Computed, never awarded. It cannot be bought, and it cannot be given to a calendar the figures do not support.

It is a position on the shelf, not a verdict. The verdict is written separately and can disagree with it.
