There are exactly three ways to lower what you pay for a chain from Saphir, and the best deal uses all three on the same order. Start with a chain like the Rope Chain, and here's how to stack every real lever without leaving anything on the table.
Lever one: pick the right code
New to Saphir, WELCOME10 takes 10% off your order, no minimum. Ordered before, COMEBACK15 takes 15% off instead, also no minimum. THANKS10, a second 10% code not tied to first-time or returning status, is the fallback if neither of those applies to your account. Checkout only takes one code, so use whichever gives you the biggest number, that's COMEBACK15 if you qualify for it.
Lever two: the free chain, which needs nothing from you
Every order includes a free chain automatically. It isn't tied to the code you use, it isn't tied to order size, and there's no separate step to claim it. Whatever code you apply, the free chain still ships. That's real value added to the order for doing nothing extra at all.
Lever three: buy a matching piece
Add a matching bracelet to the same order as your chain and an automatic discount applies to the set at checkout. It's a third savings mechanism, separate from your code and separate from the free chain, and it only shows up if the matching piece is in the same cart. That's the difference between buying a chain today and a bracelet next month versus buying both at once.
Putting it together
Build the cart first: the chain you actually want, plus a matching bracelet if you were going to buy one eventually anyway. The set discount applies once both are in. Enter your code, WELCOME10 or COMEBACK15, whichever fits your account, on the full total. Check out, and a free chain ships with the order regardless. That's a percentage off the whole cart, a discount on the matched pieces, and an extra chain, all off one order.
Why "one order" is the actual strategy
Every code here fires once per customer. Use it on a small order and that's the only shot you get, the discount doesn't come back around on your next purchase. The real move is deciding what you want first, chain, bracelet, or both, then applying the code to that full order instead of a piece at a time over separate months.
What you're getting either way
Discount or not, every Saphir chain is 316L stainless steel with 18K gold or 925 silver PVD plating, waterproof, hypoallergenic, and backed by a lifetime warranty. The codes and the free chain change what you pay. They don't change what you're wearing.
The short version
Pick WELCOME10, THANKS10, or COMEBACK15 based on your account, add a matching piece if you want one, and let the free chain ship with whatever you order. That's the whole strategy, and it costs nothing extra to run it.
A worked example
You're a returning customer eyeing the Rope Chain and a matching bracelet. Both go in the cart, the set discount applies on its own. You enter COMEBACK15, 15% comes off the combined total. You check out, and a free chain ships alongside the two pieces you actually ordered. Three items, one of them free, off a total that was already reduced twice before the code even touched it.
What this doesn't include
Two codes don't stack together, so you're always choosing one, not adding WELCOME10 and COMEBACK15 in the same order. And each code only works once per customer, so this whole approach is really a once-per-account strategy, not something you repeat every time you order. Use it on the order that's actually worth building around.
The wrong way to shop this
Buy a chain today with WELCOME10, then a bracelet next month at full price, and you've burned your one-time code on the smaller order and missed the automatic set discount entirely, since that only applies when the matching piece is in the same cart. It's the single most common way people leave money on the table here, not because the offers are hidden, but because they didn't build the full order before checking out.
Common mistakes to skip
Don't try to enter two codes, checkout only takes one. Don't assume the free chain needs a code, it doesn't. And don't check out piece by piece if you already know you want a matching set, since the set discount only shows up when both pieces are in the cart at the same time.
