You Don't Need a Note From Your Mother
It's good to have hassle free guarantees so that your customer/clients feel confident. If it's not easy to return then people feel scared and what's worst off you don't look confident in your product/service.
You should always think of ways to make easy hassle free guarantees.
You can also be creative, if you can't promise and guarantee say a percentage or return then guarantee time frame or service standards or x or x, it can be anything. The more you guarantee-the more the client/customer will feel confident-and the easier the guarantee and return/refund policy the more people will come and buy.
