September 2025 – End of Summer Savings

September sets the stage for a series of generous offers, making it one of the best months to refresh your jewellery collection or secure early holiday gifts.

Among the most attractive deals available in September is the SALE10 code, which gives customers an extra 10% off during the ongoing Summer Sale.

This promo is perfect for those seeking high-quality jewellery and watches at exceptional prices before the official autumn season begins.

Other promotions continuing through September include:

Free Next Day Delivery on orders over £125, ensuring that purchases arrive quickly and without additional cost.
0% Interest Free Finance for up to 36 months, allowing customers to spread the cost of high-value pieces without added fees.
Key Worker Discount offering a 20% price reduction for those who provide valid proof of employment in essential sectors.

September shoppers can also explore the Lab Grown Diamond Jewellery Collection, enjoy free sizing and adjustments, and benefit from a 30-day return policy for extra peace of mind.

This month is particularly attractive for customers looking for both big-ticket items and everyday jewellery essentials.

October 2025 – Autumn Highlights and New Promo Codes

October is an especially exciting month for C.W. Sellors customers.

Two brand-new promo codes debut this month, adding extra opportunities for savings before the holiday rush begins.

The first code, TREAT25, allows shoppers to enjoy 25% off full-price jewellery.
This is the perfect opportunity to purchase elegant necklaces, earrings, bracelets, and other jewellery staples at a significant discount.
The code remains valid throughout October, giving customers ample time to browse and buy.
The second new code, EXTRA20, provides up to 50% off select lines plus an extra 20% off when applied at checkout.

This combination makes October one of the most rewarding months for bargain hunters looking to secure premium pieces at unbeatable prices.

In addition to these exclusive October codes, many ongoing offers continue from September. Customers can still take advantage of Free Next Day Delivery on orders over £125, spread the cost of luxury purchases with 0% finance, and benefit from the generous Key Worker Discount.

The Garmin Fenix 8 Collection remains a highlight for watch enthusiasts, while the Lab Grown Diamond Jewellery range continues to attract eco-conscious buyers looking for sustainable luxury.
