MegaFood's main offer right now is 20% off sitewide, which gives you a straightforward discount on any size order. This works well whether you're stocking up on your regular supplements or trying the brand for the first time, though there are other options that might save you more depending on what you're buying and how you shop.
For a small first order under $100: If you're a new customer, the extra 15% off your first order may actually beat the sitewide 20%, so compare both at checkout. You can also sign up for the MegaFood newsletter to access special offers and promotions, which is worth doing if you plan to shop again later.
For any order at any spend level: The sitewide 20% off deal applies to everything in your cart right now, making it the reliable baseline to compare against other options.
If you're buying three or more products: The buy 3 products get 5% off deal is available, though the sitewide 20% off will almost certainly save you more money, so stick with that unless you're mixing it with another promotion at checkout.
If you're setting up a subscription: MegaFood offers 10% off subscription orders. This is lower than the sitewide 20%, so you should use the main deal instead unless you specifically need the subscription benefit.
At checkout, only one offer applies, so you'll need to compare which saves you the most. Calculate the final price under each option—enter the promo details for the 20% off deal and the 15% off first order if you're eligible, then pick whichever gives you the bigger discount on your specific basket.
