Sigmarite Boutique

Works well and quickly. Only needed support once and had an answer within five minutes. There are issues with the Etsy API that are out of the control of the developers but they provided workarounds and advice.

My business is entirely custom product produced on demand so an app like this is essential for me to ensure that customers are aware of the terms of service, etc. Works wonderfully, I did need a little help at one point but everything was quickly resolved. Highly recommended, and $3/month is a steal for a critical feature.
