At checkout, subject to approval — how it works
  • First instalment at purchase, the other two after 30 and 60 days. No interest and no set-up fee: 0% APR.
  • The instalment plan is granted by Klarna, Scalapay or PayPal, not by GSS Forniture. Approval, the maximum amount and the number of instalments are the provider's decision at payment time; any late-payment fees follow their terms.
  • With PayPal you choose “Pay in 3” on PayPal's own page after selecting PayPal at checkout: it needs a personal account (Business accounts are not eligible) and PayPal's longer plans — 6, 12 or 24 instalments — carry interest.
  • Availability depends on the delivery country and the provider's assessment: the methods actually available are the ones shown on the payment page.
