Halden & Rowe · Loyalty · Outdoor
Loyalty members buying a BBQ attach 2.4× the outdoor accessories of a matched non-member.
The BBQ line does not just sell to loyalty members; it converts them into a distinct trading pattern that carries into fuel, covers, tools, and food & drink for the next eleven weeks.
Observation
The pattern.
What Ana has read in the trading data — described in the language a senior analyst would use with the CEO.
Across the last two summers, loyalty members purchasing a BBQ attached 2.4 accessories on the same order and returned an average of 1.7 further outdoor visits inside 11 weeks. The comparable non-member cohort attached 1.0 accessory and did not repeat. The effect is not a discount effect — the loyalty cohort paid full price on 78% of attached lines — and it holds across every store cluster with at least fifteen BBQ transactions in the season.
Evidence
What Ana is reading.
Five to six pieces of supporting evidence. Each line is a signal, its measurement, and — where useful — a caveat.
Attach rate — loyalty members
2.4 accessories per BBQ order
Trailing two summers, n = 6,120
Attach rate — matched non-members
1.0 accessory
Same store clusters, same weeks
Full-price share of attached lines
78%
So the effect is not a discount effect
Follow-on outdoor visits
1.7 visits inside 11 weeks
Loyalty cohort only; non-members did not repeat
Downstream margin per attaching member
£74
Trailing two summers, gross of markdown
Category consistency
Effect present in every store cluster with ≥15 BBQ transactions
So not a Cork or Dublin artefact
Why this matters
What changes if leadership takes this on board.
The business consequence, framed for a board conversation rather than a metric review.
The BBQ range is currently discussed as a working-capital problem. The evidence says it is also a loyalty-acquisition engine that we are pricing as a clearance category. Every unit sold to a member is worth roughly £74 of downstream margin the current buying model does not credit to it. That reframes both the markdown decision on Ana's desk and the way BBQ is bought next season.
Commercial framing
The order of magnitude.
An honest sizing of the pattern, with the methodology stated so the number can be argued with.

£460K
downstream loyalty margin at stake · current BBQ season
How Ana arrived at this number
£74 × the 6,200 loyalty members forecast to attach the current BBQ range, before markdown erosion.
Counter-evidence
The reasons the pattern might not generalise.
The caveats Ana would raise before an executive commits an Insight to a decision. Included by design — an Insight is only useful when its limits are known.
Weather sensitivity
The 11-week window assumes a normal weather pattern
The 2024 cool summer suppressed follow-on visits by roughly 40%
Loyalty selection bias
The 2.4× attach is calibrated against a matched-propensity non-member cohort, not the raw split
Members over-index on the outdoor category to begin with

Ana's commentary
How Ana would present this in the room.
The BBQ overhang is being discussed as a cash problem. Left in isolation that framing is correct. Placed next to the loyalty attach pattern, the decision changes shape: an aggressive markdown recovers cash but discards the loyalty engine that has been running quietly for two summers.
Recommended monitoring
What Ana will keep watching.
The signals whose movement would either confirm the pattern is holding or tell us it has stopped.
- 01
Attach rate on the current BBQ cohort, weekly — divergence from 2.4 by more than 0.4 in either direction changes the working-capital argument.
- 02
Follow-on visit share inside eleven weeks, split by weather cluster.
- 03
Full-price share on attached lines — a drop below 65% would mean discount, not category, is doing the work.
