Questions about these codes

›Are these codes really working?

Yes. Each code is tested before it is listed, and the verification date is shown on every code page. If a code stops working, it is removed or marked as expired.

›What is the difference between a referral code and a promo code?

A referral code is tied to an inviter — both sides usually get a reward. A promo code is a public discount anyone can apply at checkout. Coupons work like promo codes but are often single-use or time-limited.

›Do you earn anything when I use a code?

Sometimes. Referral links can give both of us a bonus — that is the point of referral programs. Public promo codes earn nothing. Every referral link here is disclosed and marked rel="sponsored".

›Can I suggest a code for this collection?

This is a personal, hand-curated collection, so new entries are added manually. If you spot a dead code, tell me and I will re-check it.
