💰 Cadence Electrolyte Drinks — Buy 1 Get 1 After Rebate

Buy 2 qualifying Cadence cans at Walmart or Target, then text a photo of your receipt. Cadence says it will send the value of 1 can back via Venmo or PayPal within 48 hours.

Not fully free: you pay for two cans upfront and are reimbursed for only one, so this is effectively a buy-one-get-one offer rather than a 100% rebate.
