Millie's Cookies Active Deals, Sales & Codes in June, 2026

Millie’s Cookies has been a fixture of British high streets since the mid-1980s, when the first bakery opened its doors in London. Now with more than 90 shops across the United Kingdom, the chain specialises in hand-iced cookies — from bite-sized minis to giant personalised creations — that double as gifts for almost any occasion. Whether you’re after a quick treat for yourself or something more thoughtful for someone else, the range is built around the idea that a biscuit can be both delicious and personal.

The core menu spans pick-and-mix boxes starting at £8.99, giant cookies from £20, and personalised options from £27. Heart-shaped cookies and cookie pies cater to gifting moments, while the personalisation tool lets you add messages and custom designs for birthdays, thank-yous, and celebrations. You can also order via Deliveroo if you’d rather have cookies brought to your door without planning ahead.

• Free Click & Collect — order at least two hours ahead and pick up from your nearest shop with no delivery fee
• Next-day delivery — place your order by 1pm for tracked courier delivery the following day (Millie’s achieves a 99.97% success rate on next-day parcels)
• Nominated-day and Saturday delivery — choose a specific date from £5.99 (weekday) or £6.49 (weekend)
• Student and NHS discounts — both unlock 20% off with verified status
• Newsletter sign-up — 10% off your first order when you join the mailing list

With all those saving options — from demographic discounts to the codes we’ve gathered below — this page is worth bookmarking before your next cookie run.

When’s the best time to buy from Millie’s Cookies?

February is peak traffic on this page, driven almost entirely by Valentine’s Day — heart-shaped cookies and personalised gifts fly out. Easter, Mother’s Day, and Father’s Day also see limited-edition releases and bundle deals. If you’re buying for a gifting occasion, check for codes a few days beforehand; that’s when Millie’s tends to launch targeted promotions.

Should I go for Click & Collect or home delivery?

Click & Collect is free and needs just two hours’ notice, making it the obvious choice if you live or work near one of the 90+ shops. Home delivery starts at £5.99 for a nominated weekday, rising to £6.49 on Saturdays. If your basket is over £20 and you have the EXTRA20 code, the 20% saving can easily offset the delivery fee — so the maths often favours delivery for larger orders.

How do I maximise savings on a cookie gift?

Stack where you can. Start with the 20% student or NHS discount if eligible — it’s the single biggest saving available. If not, the newsletter sign-up gives 10% off your first order. Then check whether a code like EXTRA20 beats the demographic discount on your particular basket size. Since most orders only accept one code, always compare the final prices rather than the percentage headline.

Are there any catches with the promo codes?

The main one is minimum spend. The EXTRA20 code requires a £20 basket — easy enough with a giant cookie or personalised order, but a single pick-and-mix box won’t qualify. Some codes also exclude certain product lines or are limited to online orders only, so scan the terms before you get your heart set on a particular discount.
