Good For Nothing's headline offer is 25% off site-wide when you spend over £80, a straight percentage discount that rewards larger baskets. This deal makes the most sense if you're buying multiple items or hitting the minimum spend naturally, but there are other options worth weighing depending on your cart size.
If you're spending under £80, you won't qualify for the percentage discount. Newsletter signup is your best entry point here—signing up to receive special offers and promotions unlocks deals that might nudge you towards a bigger purchase. Alternatively, if you're after a specific item, the cap from £25 might be exactly what you need without any threshold to meet.
If you're spending between £80 and £105, the 25% off site-wide deal applies. On an £80 basket, you'll save £20; on £100, that's £25 in savings. This is a solid offer that beats paying full price, though the free t-shirt with orders over £80 is worth considering if you want a gift instead of a discount on total spend.
If you're spending over £105, the 25% off site-wide discount continues to grow in your favour. At £120, for example, you'd save £30 off the final bill. This makes the percentage deal your strongest option at higher spend levels, since the saving compounds with basket size.
If a free t-shirt appeals to you over a cash discount, the free t-shirt with orders over £80 kicks in at the same spend threshold as the percentage deal. You'll need to compare what matters more: the actual saving from 25% off, or getting a t-shirt as a bonus.
Only one offer applies at checkout, so compare the discounts across your actual basket before you pay. The 25% off deal will usually save you more money on larger orders, but if the free t-shirt is something you'd actually wear, that might be the better choice for you.
