Are you looking to use one of these services or are you looking to add one of them as a referral to your current site/business? I have a friend who is in the process of starting her own business that has a similar concept to those, but more unique and personalized. I would be happy to share her information with you if you are wanting to partner with someone in regard to advertising and/or exchange of services.
A little of both. I need a registry service, but like the idea of partnering with one that lists the businesses for additional exposure. I was just going through the process of testing mygiftregistry.com. I'd love to know about her business .... Thanks!
