Last updated: July 2, 2026

This Payment Policy explains how payments are handled when you purchase products from polypeptd.shop.

Accepted Payment Methods

We may accept major credit cards, debit cards, PayPal, and other payment methods displayed at checkout. Available payment methods may vary by country, order value, payment provider, and risk review.

Currency and Pricing

Product prices, shipping fees, taxes, and discounts are shown at checkout before you place an order. Unless otherwise stated, payments are processed in the currency displayed on the checkout page. Your bank or payment provider may charge currency conversion fees or international transaction fees.

Payment Authorization

By submitting an order, you confirm that you are authorized to use the selected payment method and authorize the payment provider to charge the order amount. Orders may be delayed or cancelled if payment is declined, incomplete, reversed, suspected as fraudulent, or subject to additional verification.

Security

Payment details are processed by third-party payment providers using their own secure systems. We do not intentionally store full card numbers or card security codes on our website.

Refunds

Approved refunds are returned to the original payment method whenever possible. Processing time depends on the payment provider and issuing bank.
