Can I run a discount code on my website for a festival offer without dropping my prices for everyone?

Yes, a B2C booking portal normally lets you create a discount code that only applies when the customer types it in at checkout, so the prices every other visitor sees stay exactly as they were. The code sits on top of your normal selling price and reduces it at the payment stage, which means you can promote an offer to a particular group of people without changing your whole price list.

In most setups you can control how the code behaves. You can usually set the dates it is valid between, limit it to certain products such as holiday packages or hotels only, require a minimum booking value, choose whether it takes off a percentage or a flat amount, and cap how many times it can be used in total or per customer. Some portals also let you restrict a code to a destination or a travel date range, which is handy when the offer is tied to a season rather than to everyone who visits.

The honest limit is that the discount comes out of your own margin, not the supplier's. The net rate you pay stays the same, so a code only works if your markup on that product is wide enough to absorb it. Certain airline fare types also carry supplier rules about how the fare is displayed and charged, so discounting may behave differently on flights than on hotels or your own packages. It is also worth deciding in advance how a cancellation is treated when a code was used, because the refund should reflect what the customer actually paid.

Before you advertise anything, set the code up and run one test booking with it and one without, then check the amount that reaches your payment gateway matches what you expected to earn.
