Evil Energy's sitewide discount of 10% is the main offer and works for most shoppers. Since the brand has several overlapping percentage discounts available right now, the key is to figure out which deal gives you the biggest saving on your specific basket.
For small orders under $50: The 10% off sitewide deal will save you a few dollars on most purchases. If you're a first time customer, signing up to the newsletter may give you access to additional promotions, but the 10% discount is your straightforward option today.
For orders between $50 and $150: Stick with the 10% off sitewide offer. This will save you $5 to $15 depending on your total, and it requires no signup or subscription commitment.
For orders over $150: Here you have a choice between the 10% sitewide discount and the extra 10% off offer. Both will deliver the same percentage saving on your basket, so either one gets you to the same final price. Pick whichever is easiest to apply at checkout.
If you're buying from the flash sale section: Evil Energy is running a flash sale with up to 60% off on selected products. If you're shopping items in that promotion, those discounted prices will already be significantly lower than the full price range. The additional 10% or 5% sitewide deals can still stack on top of the sale price, so compare your total basket saving between the flash sale prices alone and the sale prices plus a percentage discount. For heavily discounted flash sale items, the 10% off will likely add more value than a 5% option.
If you prefer a subscription option: The brand offers 8% off for signing up to a subscription, which gives you less savings than the 10% sitewide deal but locks in a recurring discount if you plan to shop regularly.
At checkout, you'll only be able to use one offer, so add your items to your basket and compare which discount produces the largest total saving. The 10% sitewide will beat the 5% sitewide, and the two 10% options are equivalent, so your choice comes down to whether you're shopping the flash sale or paying full price.
