Secret Sales is an off-price fashion marketplace focused on discounted branded products. It is designed for brands and retailers that want to sell fashion, accessories, beauty and lifestyle products through an outlet-style marketplace environment while protecting full-price channels and clearing stock more strategically. It is the flagship marketplace of Secret Sales Group (formerly Lifestyle Retail Group), which operates across seven European markets and took the Secret Sales name in 2026.
The marketplace is especially relevant for sellers looking to clear overstock, improve profitability and test new marketplace opportunities across the UK and selected European markets. Secret Sales is not a broad generalist marketplace: product fit, brand positioning, discount strategy and catalogue quality are key to performance.
Through Lengow, sellers can prepare their Secret Sales catalogue, segment eligible outlet products, map categories and attributes, optimise product data, synchronise stock and prices, process orders and manage each country setup through a Mirakl-based workflow.

Marketplace positioning
Who shops here?
Secret Sales attracts shoppers looking for branded fashion, beauty and lifestyle products at outlet prices. Customers often compare brand desirability, discount level, product condition, size availability, colour options, delivery promise and return conditions before purchasing.
The marketplace is particularly relevant for sellers with seasonal stock, past collections, premium branded products, fashion overstock or beauty products that can perform in a discount-led shopping environment without damaging full-price channel strategy.
Because Secret Sales is built around off-price retail, sellers should prioritise product segmentation, discount planning, variant accuracy, stock reliability, product presentation and country-level operational setup before scaling.
Fashion & apparel
Women’s fashion, men’s fashion, seasonal collections, premium apparel, branded outlet products and past-season ranges.
Shoes, bags & accessories
Footwear, sneakers, bags, leather goods, jewellery, watches, belts, sunglasses and style accessories.
Beauty & lifestyle
Beauty, skincare, fragrance, wellness, gifting, lifestyle products and complementary premium consumer ranges.
Outlet & overstock
Overstock, past collections, discounted branded assortments and outlet-focused products managed separately from full-price channels.
