I should first probably introduce the bride is Canadian and groom is American. She'll be relocating when the papers go through and they are getting married in the USA. Her family is throwing her a Jack and Jill shower soon (she won't be married until next Spring) and I'm guessing it'll be big as some people may not be able to go down South for the wedding.
The shower will have a buffet dinner and open bar
What would an appropriate cash gift be for this type of event? These are friends of ours and I want me to make sure we aren't incorrect with what we give as a cash gift especially with the being a dinner and bar.
