Kingsize is offering the 50% off sitewide promo code at the top of this page, the best pick if you want a straightforward percentage discount across men’s big and tall apparel, footwear, home and garden, sports gear and kitchenware. That sitewide code is most useful when you are buying full price items across categories. If you prefer a free gift instead, there is a separate code for a free weekender bag on orders over $75.
Big carts and full price picks, where multiple full price items add up: the 50% off sitewide promo code applies to everything on the site and takes half off your cart. For example, on a $200 order, the 50% percent discount leaves a final price of $100, a saving of $100. Use the sitewide promo code for the largest dollar saving on full price items, but note its terms: it cannot be used in conjunction with any other codes and offers.
Orders just above $75, and you want the free bag: the free weekender bag code requires spending over $75. If you value the free bag more than a lower price, apply that code. On a $90 order the free bag code leaves your total at $90 with the bag added, while the 50% off promo code would cut that $90 to $45 and save $45. Because the sitewide promo cannot be used with other codes and offers, you must choose one or the other at checkout.
Looking for the biggest possible discounts on clearance or marked items: clearance and sale deals provide the biggest markdowns on selected items. Clearance listings advertise up to 95% off and other sale lines show up to 80% or 70% off; these reductions are applied as marked on the product pages, so if your items are in clearance those sale prices will usually beat the sitewide promo. For marked clearance items the final price is the sale price shown, and some clearance promotions also state an extra 50% off sale styles which can produce far larger savings than 50% off full price, but only on sale items.
Buying bundles, tees or promotional priced ranges: special deals such as buy 2+ thermals and longsleeve tees for $16.99 each, Halloween tees from $7.98, and tees under $14.99 are automatic at checkout or priced as marked and do not need a promo code. Compare the final cart amount using those priced items against using the 50% sitewide code on full price equivalents to decide which is cheaper.
Our records show Kingsize listed 183 offers in the 12 months to October 2026, with 50 codes tested by our team in that window. Percentage codes in that period included a largest at 50% off and a typical one at 40% off, so the current 50% sitewide code matches the biggest percent we have recorded.
When choosing, compare final totals: if your items are full price, the 50% off promo code usually gives the lowest total; if your items are already on clearance with marked discounts up to 95% or on a priced deal, use the sale price instead. Remember the sitewide promo code cannot be combined with any other codes and offers, so pick the single option that leaves you the lower final price.
