I am constantly having a frustrating experience on the website. Latest example is the advertised 30VANILLA promo code is not working. Sick of this!
The code worked for me. Just ordered 2 cases.
Someone said that it doesn’t work on subscription or when used more than once. Could be the first?
Make sure also that you aren’t trying to apply it at Amazon. Doesn’t sound like you are, but thought I’d mention it. These codes are for ordering on Soylent.com only.
VANILLA30 is still active on one-time purchases only. That could be the reason the code is showing up invalid. Please reach out to customer service if you’re still having a problem and they can automatically apply it for you.
