Our take

In a culture of waste, more and more people are looking to declutter responsibly, and websites such as Vintage Cash Cow are paving the way for the circular economy. Helping customers turn their unwanted items into cash, Vintage Cash Cow utilises hundreds of in-house experts to value vintage, antique and second-hand goods that might otherwise end up on the scrap heap.

Incentivising its customers with free postal service, Vintage Cash Cow offers a hassle-free pick up and delivery and uses vintage valuers to appraise and give you an offer on your items. With a 24-hour turnaround between send-off and payment, the company has nailed the formula through cultivating a trading network of auction houses, museums, institutions and independent collectors. UK-focused at present, Vintage Cash Cow continues to scale its operations, and has landed publicity through leading newspaper recommendations.
