Is there a free membership option?
We no longer
offer a free membership option when joining GigSalad. However, if you
try out one of our paid memberships and find it doesn't quite work for
you at the price you paid, you can let the membership expire and remain
on the site with a limited free listing. These limited listings have
fewer features, less exposure, and a higher booking fee.
