WISKII is running a Club Week Sale with the 20% off sitewide promo code shown at the top of this page, and that code is the best starting point if you want a straight sitewide saving. The 20% code is best for most full priced baskets and for shoppers who can apply a single promo at checkout. If you are a student, buying sale items, or need free shipping, read on for the situations where a different offer may save you more.
Small baskets under $100. For orders of $48 to $100, the 20% off code still reduces the price but the absolute dollar saving is modest. On a $80 order, for example, the 20% code takes $16 off, leaving $64. If you are a first time customer, the 10% first order code applies but saves less: 10% on $80 is $8, leaving $72, so use the 20% code instead. Applies: the 20% off sitewide code.
Medium baskets $100 to $150. The 20% code gives a larger dollar saving here. On a $120 order, the 20% code reduces it by $24 to $96, while a 12% code would only save $14.40 (final $105.60). If you have student status and can verify it, the student 15% off applies only to students; 15% on $120 saves $18 (final $102), which is still less than the 20% code. Applies: the 20% off sitewide code; student 15% only if you are eligible.
Baskets $150 and over. If your cart reaches $150 you also gain free shipping under the free shipping over $150 deal. Use the 20% code to reduce the order total and still qualify for free shipping where the site measures threshold before or after discounts is not specified by the offer. Example: on a $200 order, 20% off brings it to $160, saving $40 and keeping you above the $150 free shipping threshold; the 12% code would leave you at $176, saving $24. Applies: 20% code plus the site free shipping threshold (note the free shipping offer is listed without a promo code).
Buying sale items. The sale collection with up to 30% off sale styles can beat the sitewide 20% code on those marked items. For a sale item reduced by 30% from $100 to $70, that $70 is lower than the $80 you would pay with a 20% sitewide discount on the original price, so pick the sale price for that item. The sale offers are valid on selected styles only and no code is required. Applies: up to 30% off sale collection for marked sale styles.
Special cases and one off deals. The two styles for €100 code applies only to selected styles and uses euros; it only helps if you have exactly two eligible items. The free shipping code listed as a promo must be used at checkout and says it cannot be used with other offers, so if you need that exact promo, do not try to stack it with the 20% code. Most of the smaller percentage codes (12%, 11%, 10%) are valid alternatives when the 20% code cannot be applied, but several of those codes state they cannot be used with other codes.
Our records for the 12 months to October 2026 show 58 offers listed for WISKII (52 codes and 6 sales), percentage codes were common and the biggest code in that period was 30% off, with a typical code near 15%. Our team ran 17 checkout tests in the 12 months to October 2026 across 17 offers, with 6 screenshots kept as proof.
When choosing, compare the final totals and take whichever leaves the lower total. If you are a student and the student 15% is available to you, compare it directly with the 20% code for your basket; if you need a specific free shipping code note its terms say it cannot be used with other offers, so you must choose between that free shipping code and any sitewide promo code at checkout.
