The Keep-It Guarantee
Let the buyer keep a named bonus, or the whole product, even after they take the refund.
Definition
What it does
The guarantee names one specific thing, a book, a report, a cassette, an analysis, or the entire purchase, and states plainly that the reader keeps it no matter which way the refund decision goes. The retention is stated as settled fact, not as a condition to earn: no extra form, no partial return, no proof required. By separating the kept item from the refund clause, the offer removes the last piece of friction an ordinary money-back guarantee still leaves behind, the fear of losing whatever came bundled with the order, or having to box something up and send it back.
Why it works
An ordinary refund promise already removes the financial risk, but the reader still pictures the hassle of returning something and the loss of whatever extras arrived with it. Naming a specific item the buyer keeps regardless erases that last worry and turns the seller's confidence into a concrete, countable gain: the worst case stops being a wash and becomes free money plus free stuff. It also plays on fairness. Once a reader believes they have already been given something for nothing, asking for their money back on top of it starts to feel greedy rather than reasonable, which quietly discourages the very refund the guarantee promises.

Examples of The Keep-It Guarantee
“If I am not completely satisfied, I may return "Bachelor's Quarters" in ten days and you will return my money. In any case, I may keep "One of Cleopatra's Nights" as my FREE gift.”
A mail-order coupon for a book club lets the buyer keep a second title as a gift no matter what happens with the first.
Why it’s this techniqueThe order card states the whole trade in one breath: 'I may return "Bachelor's Quarters" in ten days and you will return my money'. Then, with no new condition attached, 'In any case, I may keep "One of Cleopatra's Nights" as my FREE gift' settles the second title's fate no matter which way the first decision goes. The phrase 'In any case' is the tell: it explicitly detaches the gift from the satisfaction question, so returning the main item costs the buyer nothing and forfeits nothing. The bonus stops functioning as an incentive to buy and becomes proof the offer has no downside at all.

“YOURS FREE! Harry Lorayne's great new $6.00 best-seller, INSTANT MIND POWER. Yours to keep FREE, even if you return the SPEED LEARNING COURSE for every cent of your money back!”
A direct-mail piece for a memory course states the bonus book is kept even if the buyer returns the course itself.
Why it’s this techniqueThe bonus is named and priced before the refund is even mentioned. 'INSTANT MIND POWER' is 'Yours to keep FREE,' and only after that does the copy add 'even if you return the SPEED LEARNING COURSE for every cent of your money back'. The word order is the tell: ownership of the gift is settled first, so the refund clause reads as an afterthought that changes nothing about what the reader gets to keep. Pricing the giveaway at '$6.00' turns the retained item into a stated value the buyer banks regardless of what they decide about the course.

“Not only are they extending the guarantee to a full 60 days, but if you decide this program isn't for you... not only will you get a refund of the purchase price, but you DON'T EVEN NEED TO RETURN THE PRODUCT.”
A health newsletter email extends its guarantee window and tells the reader the product itself never has to be sent back.
Why it’s this techniqueHere the kept item is the whole purchase, not a side bonus. The reader gets 'a refund of the purchase price' and 'you DON'T EVEN NEED TO RETURN THE PRODUCT'. The doubled not only, but construction pushes the concession past ordinary risk reversal into pure gain, since a refund alone would already remove the buyer's downside. The capitalized final clause is the tell: it isolates the exact moment where forfeiting nothing becomes explicit and unconditional, so the guarantee reads as strictly better than free.

“I 100% Guarantee you'll love this book and the new video training or I'll return your $5.60 let you keep the book and the video training anyway. That's right, you don't even have to send anything back.”
A web sales page for a low-cost book and video bundle guarantees a refund while letting the buyer keep both items.
Why it’s this techniqueThe refund and the retention are welded into a single clause: 'I'll return your $5.60 let you keep the book and the video training anyway'. The tiny stated price, '$5.60', makes the concession look almost trivial to grant, which is exactly what licenses the generosity. The confirming line, 'you don't even have to send anything back', closes off the one action that would normally accompany a refund, so the reader is left holding the entire purchase with their money returned and nothing asked of them in exchange.

“You will get to keep the full cell health analysis, whether or not you decide to keep working with Upgrade Labs!”
A wellness-brand web page tells prospects a diagnostic deliverable is theirs to keep regardless of whether they continue as clients.
Why it’s this techniqueThe line detaches ownership of a deliverable from the buying decision itself: the reader will 'keep the full cell health analysis, whether or not you decide to keep working with Upgrade Labs'. The tell is the conditional stripped to its bare form, 'whether or not', placed directly against the thing being kept, so there is no refund language to parse at all, only a flat statement that walking away changes nothing about what the reader takes home. Naming the specific deliverable, the analysis itself, keeps the gift concrete rather than a vague assurance of goodwill.

Boundary Conditions
When it dilutes
- The offer only promises a refund, with no separate item named as the buyer's to keep regardless of the outcome
- Keeping the item is conditioned on some other action first, a partial return, a proof-of-purchase, or a support ticket within a narrow window
- The retained piece is framed as a future discount or credit rather than something already in the buyer's hands
- The guarantee itself is hedged with language like "in most cases" or "at our discretion," so the reader cannot picture the retention as certain
- There is only one item in the whole transaction, so nothing is actually being separated out to survive the refund
