The 15% off storewide promo code at the top of this page is the lead offer from Deal Society. It takes 15% off everything site only and is best if you want a simple percent off a mixed cart; the terms say the code cannot be combined with any other offers. For larger savings on specific items, the site sale on bundles of up to 40% off can beat the code when it applies.
If your cart is small ($50 or less), use the 15% off promo code. On a $50 order, for example, the 15% promo code reduces the price by 15% (percent 15%), taking $7.50 off and leaving $42.50, so you save $7.50. Free shipping is also available on all orders and will not change the choice because it applies regardless of which code you use.
If your cart is moderate ($51 to $250), still start with the 15% promo code unless every item is part of a bundles sale. On a $200 order, the 15% promo code takes 15% (percent 15%) off, which is $30, leaving $170, so you save $30. If your $200 basket is entirely composed of selected bundle items that carry the up to 40% off sale, the sale price at 40% off would be better (40% off leaves $120, saving $80). Use the sale only when the bundle discount explicitly applies to the items in your cart.
If your cart is large (over $250), compare math. The 15% promo code always gives 15% off the cart. For a $600 order, the 15% promo code takes $90 off, leaving $510, so you save $90. If the bundle sale at 40% off covers the same items, that will save more ($240 off), so choose the sale price when it applies.
Buying bundles or selected products: when you are purchasing items that are part of the bundles sale, the sale discount of up to 40% on those products can beat the promo code. For the buy 2 selected products get 10% off deal, that is only useful if you already have exactly those selected items; 10% off is less than the 15% promo code unless the promo code cannot be used on those selected items.
Our records for the 12 months to October 2026 show six percentage codes and the biggest was 15% off, which matches the current promo code, and the typical code was 13% off. The team tested six offers at checkout in the 12 months to October 2026, with two tests documented by screenshot.
When choosing between the promo code and a sale price, work out the final cart total and take whichever gives the lower total. The site terms state the promo code cannot be combined with other offers, so do not expect to stack the code with the bundle sale.
