For the customer

1. Book or buy as usual.

2. Get a code by email at the moment the shop chose: when you pay, when you pick up, or when you bring the rental back.

3. Use it next time in the discount code field at checkout. The code is yours alone and works once.

For TWICE merchants

This store runs on TWICE Commerce. The discount logic is a small Cloudflare Worker by GROU.Studio that talks to the TWICE API. You decide in one place:

• When a code is sent: order paid, rental started, or order ended.

• Who gets one: order value, listings, purchase type, channel, booking length, stock item attribute, first order only.

• How much: a percentage, fixed euros, a share of the order value as euros, or tiers by order value.

• Per listing in TWICE: the attribute *alennus* (off, 20%, 15€) overrides the amount without touching the rules.

Every code is unique, single use, written to the order for staff and sent with your own TWICE email template. Want this in your store? Ask GROU.Studio.
