Crumbl Cookies: Smaller Ranges Boost Conversion

Executive Signal Summary

Helena Bush (adm Indicia) argues that Crumbl Cookies’ weekly rotating menu of six oversized cookies demonstrates how limiting choice can increase conversion. Drawing on Barry Schwartz’s jam study and examples from brands such as Stanley, Levi’s, M&S and Pringles, the piece says curation reduces decision fatigue, encourages completionist purchases and leverages scarcity and social sharing to create ritualised repeat buying. The article presents three commercial implications: curated ranges convert better than abundant assortments (Levi’s cut range by 15% and saw conversion gains), limited editions function as behavioural drivers for loyalty, and product range design should prioritise creating shareable experiences that extend beyond the point of sale.

Sephora Expands UK Presence via Marks & Spencer Shops

Sephora is partnering with Marks & Spencer to launch 'Sephora at M&S' shops in 100 UK stores and on the retailer's website, starting next spring. The move is part of Sephora's broader UK expansion strategy, following its successful launch earlier this year. For M&S, the partnership aims to boost traffic and strengthen its beauty offering, which currently holds just over 1% of the UK beauty market. Analysts note that M&S is in a stronger position than Kohl's was when it partnered with Sephora in the US, due to its existing food traffic and younger consumer traction. The UK beauty market is worth roughly $7 billion, growing 1.2% annually.
