New-account credit
Automatic, no code
Applied at registration or first payment. The most reliable discount because it is tied to the account, not to a campaign.
Coupons · mechanism over codes
Kakobuy coupons: what works, what expired, and how to check.
A coupon page that lists dead codes is worse than no page. This one shows where codes come from, how to test one in about a minute, and what to do when it fails.
Three types
The ticket ledger
Three mechanisms, three different rules. None of them is a promise that a specific code is live today.
Campaign code
Time-boxed
Announced on the partner’s own banners and help pages. It has an expiry and often a category or line restriction.
Shipping credit
Line-specific
Discounts a shipping line or weight band, not the item price. It can disappear when you change the line.
The 60-second test
How to test a code without paying
-
1
Add the item to the cart
Do not pay. The coupon field is usually inactive until the cart has an item.
-
2
Paste and apply
Enter the code in the discount field. Watch the total, not the toast message.
-
3
Read the discount row
A working code changes the total or adds a discount line. A dead code leaves it unchanged.
-
4
Remove it if nothing moved
Do not pay a higher total to keep a broken code. Try the new-account credit instead.
Why codes die
The four things that kill a code
Compare before you chase
Coupon vs invite code vs shipping credit
| Mechanism | What it discounts | Typical trigger | Can it stack? |
|---|---|---|---|
| Coupon code | Order or category | Campaign, newsletter, partner banner | Sometimes, per checkout rules |
| Invite / referral code | Account credit or first order | Registration through a link or code | Usually not with a coupon |
| Shipping credit | A line or weight band | Line promotion, seasonal event | Sometimes with an item coupon |
Myths
Four coupon myths
“The bigger the code, the better”
A 20% shipping discount on a $10 parcel is smaller than a $5 item credit. Compare the total, not the percentage.
“Codes never expire”
They do. A code copied from a video last month is usually dead.
“Support will honor it”
Sometimes, but do not plan a purchase around a screenshot. The checkout is the contract.
“Stack everything”
Most checkouts allow one item discount and one shipping discount at most. Read the rows.
Questions
Four questions about coupons
Why do you not list codes?
Because a code can die between publication and your checkout. A list of expired codes wastes your time and makes the page untrustworthy. We explain where codes come from and how to test one.
What is the difference between a coupon and an invite code?
A coupon usually discounts an order or a shipping line. An invite or referral code is tied to an account relationship and may credit both sides. They are not interchangeable.
Can I stack a coupon and a shipping credit?
Sometimes, but the checkout decides. Add one, read the discount row, then try the second. If the total does not move, it did not stack.
What should I do if a code fails?
Do not pay. Remove it, check the expiry and the line restriction, and try the new-account credit instead. A code that fails is not a reason to accept a higher total.
Check the total, then decide
A coupon is only real when the total moves. Open the partner coupon page and test it.
