Purchases and this website
Because there is no checkout, the operator never charges a visitor anything - which is why there is no refund process.
Buying somewhere else
Where a visitor follows a link and then buys something, the transaction belongs to that seller, and its terms on price, cancellation, and refunds are the ones that apply.
