Short answer: a real credit card usually won't work
Cannabis is still illegal under federal law, and the card networks act on that. Visa and Mastercard both bar cannabis purchases from running on their rails, and American Express and Discover follow the same posture. So when a dispensary site flashes a credit card logo at checkout, one of three things tends to happen: the charge declines, it gets coded as a cash advance with a fee and immediate interest, or it clears once and never again.
That does not make online ordering pointless. It means the payment step is the part worth studying before you build a cart.

What actually clears at checkout
Legal retailers in the US lean on a small set of workarounds, and each one has tradeoffs.
- PIN debit through a cashless ATM terminal. Your purchase is rounded to a $5 increment and shows up as an ATM withdrawal. It works at many registers, but you eat a $3 to $5 fee.
- Pay-by-bank apps. Services like CanPay, Aeropay, and Dutchie Pay pull straight from your checking account. No card network involved, so nothing gets blocked. You link a bank account once.
- Cash at delivery or pickup. Still the most common option, and often the only one for first-time customers who have not linked a bank.
- Store credit or loyalty balance. Some shops let you preload an account and draw down against it.
How to vet a retailer that claims to take cards
I start with the license. Every legal dispensary publishes a state-issued license number, usually in the site footer next to a physical address and phone number. You can match that number against your state's licensee lookup in about two minutes. If it is missing, or the address is a mailbox store, close the tab.

Then read the payment disclosure before you type a card number. If the site warns that the charge will appear under an unrelated company name, that is a processor hiding from the networks, not a convenience. It also means your dispute rights are thin.
Finally, watch for language about shipping across state lines. Interstate cannabis sales are not legal, so any site promising to mail flower to another state is either misrepresenting the product or breaking the law.
Parameters worth comparing
- Payment fee: cashless ATM runs $3 to $5, or roughly 2 to 4 percent of the order.
- Order minimum and delivery minimum, which are often different numbers.
- Where ID verification happens, at checkout or at the door.
- Delivery radius and time windows, since a wide radius usually means a slower window.
- Whether taxes and excise fees appear before the final screen.
- Replacement policy for damaged flower, a wrong strain, or a missing item.
- Whether loyalty points survive a payment method switch.
Pitfalls that cost you money
- Cash advance coding. Your issuer can charge a fee plus interest from day one, with no grace period. A $60 eighth can cost $70 by the time the statement lands.
- Chargebacks backfire. Disputing a cannabis charge can get your account flagged, and you may lose anyway because the transaction is federally illegal. You have less recourse than you think.
- Prepaid and gift cards. They often fail because they cannot do PIN debit or because address verification does not match.
- Requests for a photo of your card or a Zelle, Venmo, or Cash App transfer to a personal handle. That is a scam pattern, not a payment option.
- Fly-by-night processors. If the payment app disappears, so does your dispute window.
- Third-party delivery apps that list cannabis but route payment through a shell merchant. You get no receipt you can use.
Before you hit pay
Confirm the license number. Read the fee line. Prefer pay-by-bank or cash over anything that touches a credit card. Keep the order confirmation email, because it is your only proof if the bag shows up short. And if a site makes the payment step confusing on purpose, that is your signal to buy somewhere else.
