Original Penguin runs several overlapping sale promotions, with the headline offer being up to 80% off clearance sale items. If you're shopping clearance, sale sections, or a mix of both, you'll want to compare these discounts against your basket to see which saves you the most at checkout.
Clearance shopping: Original Penguin's clearance sale is strong right now. If you're filling your cart with clearance items, check whether the up to 80% off clearance sale or the up to 85% off clearance sale applies to your selection, since one of these will almost certainly beat the other percentage deals on offer.
Buying from the sale section: The sale section has a few promotions running at once. If your basket is mostly sale-priced items, compare the extra 10% off sale items deal against the up to 72% off sale styles and the up to 85% off clearance sale offers to see which stacks the best discount on your specific selection.
Small orders under $50: If you're spending less than $50, take a look at the clearance and sale percentage offers first, since they'll likely save you more than free shipping alone would. Free shipping on orders $50 and over is useful if you're close to that threshold and want to skip the shipping cost, but the percentage discounts will typically outpace it on smaller carts.
Orders $50 and above: Once you hit $50, free shipping becomes available, but the clearance and sale discounts still apply and will probably save you more money overall. Compare what you're actually saving with the percentage deals versus the free shipping benefit and go with the larger saving.
First time customers: If you're new to Original Penguin, signing up to the newsletter will get you access to special offers and promotions beyond what's listed here, which could be worth doing before you shop if you don't have an account yet.
Labor Day timing: Original Penguin is also running a Labor Day sale with up to 60% off sale products. If your cart is timed around that holiday and consists of sale items, this deal might apply alongside the others, so check all available discounts at checkout.
Remember that only one offer applies at checkout, so compare all the available discounts in your basket and select whichever one gives you the biggest saving. The percentage deals on clearance and sale items tend to outperform free shipping on larger orders, but run the numbers on your specific cart to be sure.
