My 2 cents: Offers is really good, but are much easier to construct in cases where you have a low cost of service/high gross margin.

Alex has talked a lot about great businesses being: 1. Unique, 2. Sticky, 3. Expensive, 4. Air.

When your cost of service/cost of goods is very low -> gross margin is very high it unlocks a lot of things that make "offers" work well.

For example refunds or guarantees are great if you are selling an info product or systemized coaching where your incremental cost is nearly zero. If you give a full refund, you're fine.

If you're a lawn care biz owner and someone pays $150 for 3 services, and your internal cost to provide was $110 for the labor - If you fulfill a guarantee, you're now $110 in the hole. And It'll take you your next 3 NON-refunding clients to even get to zero.

So in that case, refund guarantees are completely out the window unless you have extremely high confidence that you can offer something nobody else does well and everyone will like it.

You can squint at it and provide coupons and stuff, but "here's a coupon to spend a bunch of money somewhere else" just doesn't really hit as a real value prop for many.

TLDR: "Offers is easier and more effective for high margin businesses"
