Mommesilk has a strong selection of codes and clearance sales running right now. The 20% off code at the top of this page is the headline offer and works on the full Mommesilk range of mulberry silk sleepwear, pillowcases, duvets, bed linen and accessories. However, the best choice for your basket depends on what you are buying and how much you plan to spend.
On a smaller order under $199: The 20% off code gives you a straightforward saving on anything in the Mommesilk range. If you spot sale items in the clearance section, compare the two. The up to 65% off clearance sale beats 20% on discounted pieces, but 20% off full price items is usually better than a small clearance markdown.
On an order of $199 to $299: You now have options. The 20% off code still works across the full range. But if your basket totals $199 or more, the $20 off code for orders over $199 may save you more, depending on what you are buying. On a $250 order, for example, 20% off brings the price to $200 and saves you $50, while the $20 off code saves you $20. The percentage code wins here. Switch to the $50 off code only when your order crosses $299.
On an order of $299 or above: The $50 off code for orders over $299 becomes your most powerful single discount. On a $300 order, it saves you $50 and brings your total to $250. The 20% off code would only save you $60, so that would be stronger. Work out both and use whichever leaves you with the lower final price.
On a two item purchase: If you are buying two items of the same category, check whether a buy one get one code applies. The buy one get one 40% off code on sleepwear and clothing saves you 40% on the cheaper item when you buy two. On two sleepwear pieces priced at $100 each, for example, you pay $100 plus $60 (40% off the second), totaling $160 and saving $40. This beats the 20% off code on the same $200 order, which would save $40 as well, but is worth testing against percentage codes on mixed purchases.
When buying clearance items: The up to 65% off clearance sale is automatic with no code needed. Clearance discounts apply to selected stock only, so not everything qualifies. If the pieces you want are in clearance, the existing markdown usually beats any code. But always check the full price too: a 20% off code on full price stock sometimes saves more than a small clearance discount.
On orders with free shipping in mind: Free shipping applies to orders over $69 after any discount is applied. This does not stack with other offers, so plan your basket first, apply your chosen code, and check whether the reduced total still hits $69. If your basket after a code falls below $69 and you need free shipping, you may need to add more items.
