The 18% off sitewide code is DiscountMugs's main offer right now, and it works across all categories from fashion to home and garden. For most shopping trips, this is the code to reach for. But you might save more with a different code depending on what you are buying and how much you spend.
Buying under $100. If your total is under $100, the 20% off your entire purchase code saves you more than the 18% sitewide offer. On a $75 order, for example, 20% off leaves you paying $60, a saving of $15, versus $61.50 with the 18% code. Use the 20% code here.
Buying $100 to $300 on a mix of items. The 18% sitewide code remains the best choice for a general order across categories. On a $200 basket, it saves you $36, taking your total to $164.
Buying only bags. The 20% off all bags code gives you the same saving as the sitewide 18% code would (20% versus 18%), but this code cannot be combined with other offers. Use it if you are buying bags only. If you are mixing bags with other items, stick with the 18% sitewide code, which applies to your entire order.
Buying $100 or more on office supplies. If your order is $100 or more and includes notebooks, pens, ceramic mugs and stress balls, compare the 15% off code for those categories against the 18% sitewide code on your full basket. On a $100 order of office items, 15% off saves you $15; 18% off saves you $18. The sitewide code still wins.
Buying $500 or more. At $500 or more, check the $50 off code for orders over $500 against the percentage codes. The $50 code gives you a $50 saving and applies to custom drinkware orders (it excludes blank items). On a $500 order, $50 off leaves you paying $450. The 18% sitewide code would save you $90 on the same basket, bringing it to $410. The percentage code saves more. Use the 18% code.
Sale items. The up to 70% off sale products deal is a separate markdown and is not a code. If you are buying sale items at 70% off, that is the discount shown at the till. The codes you redeem at checkout (including the 18% sitewide code and others) may apply on top, but the offer terms do not confirm this. On a sale item marked down 70%, an additional 18% off would lower it further, but test the code at checkout to confirm it works with marked down prices.
First time newsletter signup. If you are shopping for the first time at DiscountMugs and haven't used a code before, signing up to the newsletter may open up other offers in due course. But the codes available on the page right now are the best current deals, and you don't need to wait for an email.
DiscountMugs has listed 116 offers in the 12 months to October 2026, and our team tested 90 codes at checkout in that time, so these pages turn over regularly. The 18% sitewide code matches the biggest percentage code DiscountMugs has offered in the past year.
When you have worked out your basket size, pick the code that saves you the most: start with the 18% sitewide offer as your baseline, then check the 20% code for smaller baskets, the category specific codes if you are buying from a single department, and the $50 fixed discount if you are spending over $500. Whichever code leaves you with the lower final total is the one to use at checkout.
