BEAUTY BAY Coupons & Promo Codes – October 2026: TREAT, BB20 and Half-Price Palettes
BEAUTY BAY prices are already low — a 42-shade palette for $30 — but shipping a parcel from England to your door adds up, and so does "just one more palette." The good news: the store is showing two real codes on its US site right now. Here's how to use them and every other saving we found in October 2026.

Is There a BEAUTY BAY Promo Code?
Yes — two of them, both printed on BEAUTY BAY's own US product pages when we checked:
- TREAT: "15% off when you spend $80."
- BB20: "Save 20% when you buy 3 or more By BEAUTY BAY products."
One catch: BEAUTY BAY's promotion rules allow only one discount code per order, and codes are generally applied against the regular price, not on top of items that are already reduced (unless a promotion says "extra"). So you'll pick one. Any newer code will appear on our BEAUTY BAY deals page.
Deal 1: TREAT vs. BB20 — Which Should You Use?
| Your cart | Better code | Why |
|---|---|---|
| 3 × 42 Colour Palettes ($90) | BB20 | 20% off saves $18 vs. $13.50 with TREAT |
| 2 palettes + a blush duo ($76) | BB20 | TREAT needs $80; BB20 needs only 3 own-brand items |
| $100 of other brands | TREAT | BB20 only covers By BEAUTY BAY products |
| Mixed cart, 2 own-brand items | TREAT | BB20 needs 3+ own-brand products |
Not every product qualifies for BB20 — product pages show a "Buy 3 save 20% code BB20" tag on the ones that do.
Deal 2: Newsletter Sign-Up
The US site's banner reads "Sign up to our newsletter and get 15% off." It's a good fit for a first order that doesn't reach $80, or for a cart of other brands. Remember it's still one code per order.
Deal 3: The Offers Section
| Product | Was | Sale price | You save |
|---|---|---|---|
| The Collector's Edition Palette | $60 | $30 | $30 |
| Make Face Multi-Use Complexion Palette | $26 | $20.80 | $5.20 |
| Liquid Cream Blush | $13 | $9.10 | $3.90 |
| Chamomile + Oat Lipid Cleansing Balm (90ml) | $13.25 | $9.15 | $4.10 |
| Clearance – Does It All Cheek Palette | $15 | $9 | $6 |
There's also a value kit: The Ultimate Makeup Treats ($58.50) packs ten By BEAUTY BAY favorites — including the new Dusky Neutral 20 Colour Palette, a special-edition All Hours Lip Stain and a mini High-Key Volume Mascara — in a velvet pouch and beauty bag.
Deal 4: Free US Shipping Over $125
US Tracked delivery is $15 and arrives 4–8 days after dispatch. Spend over $125 and it's free. With a code applied, a cart of four palettes plus brushes gets you there while still saving 15–20%.
Deal 5: The 100% Obsessed Promise
Not a discount, but it protects your money: By BEAUTY BAY products come with 60 days to return them for a full refund of the price you paid, minus delivery costs, even if used (terms apply). Regular returns, by contrast, need to be unopened within 30 days, and international customers pay return postage to the UK.

BEAUTY BAY Coupon FAQ
What does code TREAT do?
When we checked, TREAT gave 15% off orders of $80 or more on the US site.
What does code BB20 do?
BB20 saves 20% when you buy 3 or more qualifying By BEAUTY BAY products.
Can I use two codes on one order?
No — only one discount code can be used per order, and lower-value codes won't apply to items that already have a better promotional price.
How much is shipping to the US?
Tracked shipping is $15, free on orders over $125, with delivery 4–8 days after dispatch.
The Bottom Line
The smartest BEAUTY BAY order this month is three or more own-brand palettes with code BB20 — or a bigger mixed cart with TREAT — pushed past $125 for free US shipping, with a half-price Collector's Edition on the side. Check our BEAUTY BAY deals page before you buy.
