Payment Methods

Checking out should be as easy as setting up your screen. STWUI supports a wide range of secure payment options — use whatever works best for you.

Your payment information is protected at every step. We do not store full card numbers on our servers, and all transactions are processed through trusted, industry-standard payment providers.

Accepted Payment Methods

Credit & Debit Cards

Pay securely with any of the following major cards:

• Visa
• Mastercard
• American Express
• Diners Club
• Discover

Your card details are encrypted at checkout. STWUI does not collect or store your credit or debit card number on our servers. For questions about a specific charge or transaction, please contact your card-issuing bank directly.

Digital Wallets

Skip the card entry — fast, secure checkout with your preferred digital wallet:

• Apple Pay — Pay with Face ID, Touch ID, or your Apple Watch. Your actual card number is never shared with STWUI; Apple Pay transmits an encrypted token specific to each transaction.
• Google Pay — Secure checkout using a virtual account number linked to your payment method. Your real card number is never sent to the merchant.
• Amazon Pay — Use the payment method and shipping info already saved in your Amazon account to check out quickly on STWUI.com.
• PayPal — Select PayPal at checkout to complete your purchase securely on PayPal's own page. No PayPal account? Choose Pay with Debit or Credit Card on the PayPal checkout page to pay as a guest.
• Venmo — Pay directly from your Venmo balance or linked bank account at checkout.

Wallet availability may vary depending on your device, browser, and region. The options available to you will appear at checkout.

Shop Pay — Accelerated Checkout

Shop Pay is Shopify's accelerated checkout that saves your email, shipping address, and payment info for faster future purchases. Enter your email at checkout and opt in to save your information — next time, you're one tap away from done.

Shop Pay also encrypts and secures your data, and your saved information is never shared with STWUI or third parties without your permission.

Buy Now, Pay Later — Shop Pay Installments & Affirm

Want to spread the cost? STWUI supports Shop Pay Installments, powered by Affirm, so you can pay for your gear over time.

• Split your purchase into 4 interest-free payments (for qualifying orders)
• Or choose monthly installment plans for larger purchases
• Rates from 0% – 36% APR, depending on your eligibility and selected plan
• A down payment may be required for some plans

How it works: Select Shop Pay at checkout, then choose the installment option. Affirm will run a quick eligibility check — it takes seconds and won't affect your credit score to check. If approved, you'll see your available plans and confirm your schedule before completing the purchase.

Payment options through Shop Pay Installments are provided by Affirm's lending partners. See affirm.com/lenders for details. State-specific notices: affirm.com/licenses.

Payment Security

STWUI.com uses SSL encryption across all pages and checkout flows. All payment transactions are processed through trusted, PCI-compliant providers. We do not store your full credit card number, CVV, or bank account details on our servers at any time.

If you ever notice an unexpected charge or have concerns about a transaction, contact us at support@stwui.com and we'll help you sort it out.

Sales & Use Tax

STWUI is required by law to collect Sales & Use Tax on orders shipped to certain U.S. states. If applicable, the tax amount will be calculated and displayed after you enter your shipping address at checkout — before you confirm payment.

Sales tax is calculated based on your shipping address, the items in your order, and applicable state and local tax rules.

Is sales tax refundable? If an eligible order is refunded, any applicable sales tax paid on that order will also be refunded in accordance with state tax rules and our Refund Policy.
