WhereLight's back to school sale is running strong through early September, with the featured $75 off voucher available on orders over $200. This is the best value for shoppers spending that amount, but you'll want to compare several options depending on your basket size to make sure you're getting the largest possible discount.
Spending $70 to $99: The $20 off voucher on orders over $70 gives you a straightforward saving. If you're a new customer, the 30% or 35% off new customer codes may deliver more, depending on your total—calculate both to see which works better for your purchase.
Spending $100 to $149: You have multiple routes here. The $35 off voucher (orders over $100) is reliable, but the 25% off code (orders over $69) could save you more if your basket qualifies. New customers should compare the 30% or 35% off new customer discounts against these fixed amounts to find the bigger saving. The free shipping on orders over $69 also stacks with any code, so you'll save on delivery too.
Spending $150 to $199: The $40 off voucher for orders over $150 applies here, but the 25% off code for orders over $69 might beat it depending on your exact total. New customers have the same advantage with percentage discounts. The bundle offer of 3 pairs for $169 is worth considering if you're buying frames and lenses.
Spending $200 or more: The headline $75 off voucher is your best value, saving you $75 on the spot. The $55 off code also qualifies at this spend level, but the $75 voucher wins. If you're shopping specifically for frames, the 35% off frames code could outperform both depending on your exact cart total—calculate this before checkout.
Special situations: If you're buying just one pair of frames, the 40% off first pair code offers strong savings. The buy one pair, get 50% off lenses deal works well if you're purchasing both frames and lenses. The back to school sale items showing up to 80% off are worth browsing before you apply any code, since you may find better deals on specific products without needing a voucher at all.
Remember that only one voucher code applies at checkout, so if you have multiple options available in your basket, compare the savings each delivers and use whichever produces the larger discount. Always check the brand's website for the full terms before you shop, as some offers have additional exclusions or restrictions.
