Interesting article. I am glad that they said cash is the most popular gift since a lot of SSes on here don't seem to comprehend that.
We don't get invited to too many weddings since H is older and I'm approaching "older", but I normally have to spend at least $600 on airfare because we don't live near family or close friends. The last wedding we went to was my brother's and we spent well over $2k for flights, attire, gifts, etc and we stayed at my mom's house!!!
