How and when you are charged, which methods we take, and what to do when a payment does not behave.

- Apple Pay and Google Pay.
- PayPal.
All payments are processed by Shopify Payments and its partners over an encrypted connection. We never see or store your full card number.
When you are charged
Placing an order creates an authorisation on your card — a hold, not a charge. We capture the payment when your order is picked and dispatched. If an item turns out to be unavailable, the captured amount reflects only what we actually sent.
Authorisation holds
An authorisation can appear in your banking app as a pending line for a short period even if the order is cancelled. Banks usually release these within 3–5 business days. We cannot release a hold sooner than your bank allows.
Payment failures
A payment can fail for several ordinary reasons: an expired card, insufficient funds, a billing address that does not match your bank's records, or your bank's fraud checks. Check those first, then try again or use a different method. Repeated failures are worth raising with your bank before contacting us.
Duplicate charges
If you see the same amount twice, it is most often one real charge plus one pending authorisation that has not yet dropped off. Give it 3–5 business days. If both are still there afterwards, send us the order number and the dates and amounts, and we will investigate and refund any genuine duplicate.
Refunds
Refunds always return to the original payment method — we cannot redirect them elsewhere. We process approved refunds within 2 business days; your bank typically posts them within 3–10 business days. See the Return & Refund Policy.
Taxes
Sales tax is calculated at checkout based on your delivery address and the tax treatment of each item — many grocery staples are taxed differently from household and personal-care goods. The exact amount is always shown before you pay.
Receipts and invoices
An emailed receipt follows every order. Past orders and their receipts live in My Account. Need an itemised invoice for business or expense purposes? Email us with the order number.
Pricing
Prices are shown in US dollars and include any applicable deposit where required by state law. Promotional prices apply while stock lasts. If a price is displayed in error we will contact you before charging and you are free to cancel.
Problems with a payment
Email accounts@miakarts.com or call +1 (844) 520-1414 with your order number. Please never send full card details by email — we will never ask for them.
