Preston Herb Co Discount Codes & Promo Codes

PHC’s checkout only lets you enter one code in the discount box, so you can't stack promos. If you try adding a second, it just overwrites the first. Your best bet is using a standard 10% first-time code on regular flower, or wait for holiday drops when prices get cut sitewide automatically.

Preston Herb Co gives 20% off for first responders, but you have to verify through their portal before paying. Do not expect it to apply automatically. If the verification prompt glitches, just email support with your credentials. Also, keep in mind the generated code will not stack with their bundle deals or sale items.

Preston Herb Co keeps their reward tiers hidden until you actually make an account and log in. Points usually populate in a popup widget at the bottom right during checkout. Honestly, the point conversion is pretty slow—you’re usually better off just waiting for their holiday email blasts for 15% or 20% off.

Preston usually runs around $8 to $10 for standard USPS Priority at checkout, but they bump you to free shipping once you hit the $100 mark. Heads up though: make sure you uncheck that Route package protection toggle in your cart before paying if you don't want the extra buck or two tacked on.
