Valid Letterbox Gifts discount codes for September 2026

1. Pick a code that works for the gift set you want. 2. Click it to copy, then head to Letterbox Gifts in a new tab. 3. Add your items to the basket — they do all sorts of letterbox-friendly stuff: birthdays, anniversaries, new homes, thinking of you, etc. 4. Go to checkout and find the discount code box. 5. Paste your code in and apply. 6. If it's valid for your order, the price should drop before you pay.

First, check the code is still valid. Their codes are one use per customer, so if you've used it before, that might be why. Also check what's in your basket — their codes exclude subscriptions, brownies, and macarons. Sometimes the code just doesn't cover the product you picked. If it still won't apply, try removing it and typing it in again carefully. A small typo can mess it up. Annoying, but common.

Yes, they offer free Tracked 48 delivery on orders over £25 to a single UK address. If your order is under £25, Tracked 48 costs £4. They also have Tracked 24 for £5, and Guaranteed Special Delivery for £8. If you're trying to get the best value, it's usually worth nudging the basket over that £25 mark.

Yes — sign up for the newsletter and you get 10% off your first order. We think that's a nice little saving, especially if you're trying Letterbox Gifts for the first time. It's one of the simplest ways to save without hunting around too much.

No, you can't stack them. Their codes are one use per customer and can't be combined. So if you have more than one code, pick the one that gives the biggest saving for your basket. That's usually the safer bet anyway.

Letterbox Gifts delivers within the UK only. Options: Tracked 48 (free over £25, £4 under), Tracked 24 (£5), Guaranteed Special Delivery (£8). Orders before 2pm Mon–Fri usually ship same day. Macarons and brownies go next working day. No dispatch on weekends or bank holidays. You can request a specific delivery date in the basket — handy for timing a birthday properly.

Yes, there's a 20% NHS discount through Health Service Discounts. You need to be a member to access it, so it's not a code anyone can use. Still, a decent saving if you qualify, and we always like a proper verified route rather than guessing at checkout.

They accept returns within 30 days, but only for faulty or damaged items. If that happens, they provide a prepaid returns label. They don't do change-of-mind returns, so double-check your order before buying. A bit strict, but at least it's clear.
