Gas4U referrals

Share your referral link

Send one link to friends. Each friend claims with their own email and Eircode, so the same referral cannot be used twice in one household.

Share this link by WhatsApp, email, or message. Your friend enters their own email and Eircode to claim their discount.

Use the same email you used for your subscription order. We use this to find your referral link.

Claiming a friend discount will ask for your email and Eircode so the same household cannot use the same referral twice.

Used only to prevent repeat use of the same referral in one household.

Referral access unlocks after your first subscription order.

Use the email from your subscription order to get your referral link. If you have just ordered, wait a minute for Shopify to process it and try again.
