My cousin and his FI are having a Jack and Jill Greenback Shower, the weekend before my FI and I's wedding. Normally this would not be as big of a deal to give but we are already strapped for cash due to our wedding being the following weekend and I have tried to find a registry online and there is none. And my mom is guilt tripping me because my aunt is helping with my shower...the weekend before theirs. What should I do?
