Defender Shield is running a Back to School Sale with 15% off when you buy 2 or more items—a solid choice if you're picking up multiple products at once. The brand also has several other deals running simultaneously, so your best saving depends on what you're purchasing and how much you spend.
Buying a single item under $125: The 20% off all products deal beats everything else here, giving you a straightforward discount on your entire purchase. If you're a first time customer, you might also consider the $5 off first order option, though the 20% discount will almost certainly save you more.
Buying 2 or more items: The Back to School Sale's 15% off kicks in automatically when you hit two items, making it the easiest option to claim. However, compare this against the 20% off all products deal—if that's still running, the 20% will save you more money than the 15% threshold offer, so go with that instead.
Higher spend baskets of $125 and above: If you're spending $125 or more, factor in the free shipping offer alongside your discount. Take whichever gives the biggest saving: either 20% off your entire order, or the Back to School deal at 15% off two or more items plus free delivery. The 20% off will typically win here unless you're buying exactly two items and shipping costs are substantial.
Browsing sale items: Defender Shield has up to 65% off selected items and up to 60% off selected products running simultaneously. These clearance deals are worth checking first if you're flexible on what you buy—they may beat any percentage discount on full price items, especially if you're hunting for bargains across multiple categories.
Only one offer applies at checkout, so once you've added items to your basket, check which deal produces the largest discount and take that one. The percentage discounts (20% off all products, 15% off two or more items, and the up to 65% or 60% off selected stock) will typically outpace the $5 first order option unless you're spending very little.
