Where to type a discount code on the checkout screen, how to read the discount row in the summary, how many periods the code lasts and when it is refused.
Last updated: September 30, 2026
You have a discount code and you want to see the amount actually drop. Codes are applied on the checkout screen, and the discount appears as its own row in the summary box before you place the order. This guide gets the code into the right box and makes the duration clear.
The code is upper-cased for you, so typing it in lower case is fine. If the code is valid a new row joins the summary and the Total drops. If it is not, the line "This code is not valid." appears in red under the box and the amount stays the same; you can still place the order, just without a discount.
The rows in the summary box sit in this order:
A discount is always taken off the subtotal and the tax is recalculated on the new subtotal. That is why a 100-lira discount lowers the total by exactly 100 lira when prices include VAT; no rounding gap appears.
A code discount and an unused-time credit can apply together. Together they never push the total below zero; the amount bottoms out at nil.
💡 Tip: If the total reaches zero, the payment step never opens. The order is confirmed on the spot and the order page reads "Your order is confirmed; your plan is active."
There are two kinds of code, and their effect on the total is calculated differently.
A percentage discount is a percentage of the subtotal. If a plan costs 1,200 lira including VAT at a 20% rate, the subtotal is 1,000 lira. A 25% code takes 250 lira off that subtotal; 20% VAT is added to the remaining 750, and your total comes to 900 lira. So on a VAT-inclusive price the discount really is exactly 25%.
An amount discount is a fixed figure in one currency. When prices are entered including VAT, the code is calculated so it lowers the total by the figure it states: "200 lira off" reduces the total by exactly 200 lira, not by 166 because of VAT.
That is why the Total row in the summary box is always the real amount you will pay; no extra arithmetic is needed. If the figure is not what you expected, look at the Plan price row first: the price changes with the currency you selected and with your Monthly / Yearly choice.
The unused time credit works the same way and is applied after the discount code: the code comes off first, then the value of your unused days.
Under the discount row, small type states how long it lasts. There are three possibilities:
A code with a duration is stored on your subscription. Even if the code is switched off later, a discount that has already started runs until its duration is up; the remaining period count drops by one at each renewal.
On a renewal or upgrade order, if you type nothing into the box and your subscription carries a running discount, that discount is applied automatically. The code's name still shows in the summary; you do not have to enter it by hand.
The amount on the Next payment row of the Plan tab uses the same calculation: with a running discount you read the discounted amount, so there is no surprise.
Enter a new code and it replaces the old one, with its own duration starting from scratch.
A code is refused for one of these reasons:
If a code becomes invalid between the moment you applied it and the moment you place the order, the order is not quietly opened without it: the panel says "This code is not valid; remove it and try again." Clear the box, press Apply, then place the order again.
If a code you believe should work keeps being refused, re-read the conditions where you got it; if that does not explain it, contact our Support team.
