Grab a referral link from Reddit; it saves you $20 on a $50 cart. Just paste it into the discount code box at checkout. Heads up: it only works on one-time purchases and won't stack with subscription discounts. Hit the $50 minimum with powder tubs to maximize the savings.

Just heads up on Soylent: you can cancel directly in the "Manage Subscriptions" tab, but watch the renewal date. Once that charge hits, warehouse fulfillment locks in and support won't refund or stop it. If you're on the fence, just hit "Skip" or push the date back two weeks instead.

You can get the 10% student discount through Student Beans at checkout, but honestly, it’s rarely worth it. It only applies to one-time purchases, not recurring subs. You're better off just setting up Amazon Subscribe & Save with five items to get 15% off, or using a new email for their standard 20% off welcome code.

They rarely run straight promo codes on soylent.com outside Black Friday. Honestly, just use a burner email for their 20% welcome pop-up, or toggle the "Subscribe" box at checkout to get the lower rate—you can cancel right after it ships. Otherwise, Amazon Subscribe & Save usually beats their direct prices anyway.
