The 15% off discount code at the top of this page is the lead offer at Joom, but it only works if you are shopping in a physical store, so you need to choose based on how you plan to pay.
Shopping in a Joom physical store: Use the 15% off code, which applies to everything you buy in store. This code does not work online, so use it only when you pay in person at a shop location.
Buying full price items online: Choose the extra 10% off sitewide code for your entire online order. On a €100 basket of regular priced items, you would save €10, bringing your total to €90.
Buying sale items online: If you are shopping for selected items in the Black November sale, compare the two routes: the 10% off sale items code and the marked down prices in the sale itself. On a €80 sale item, the 10% off code reduces it to €72, a saving of €8, whereas the sale price shown on the product page may already be lower. Work out the final cost both ways and pick the one that costs less.
Newsletter signup: If you do not have a code that works for your purchase right now, signing up to the Joom newsletter puts you in line for special offers and promotions sent to your inbox.
