Not sure this is at the right spot, but I think you ladies can help me out. Our nephew is newly engaged for Christmas to his girlfriend of a couple years. Her family is throwing a big engagement party next month, but there is no set wedding date. They are talking about the wedding being in three years or so. I googled engagement party etiquette and it looks like gift are very optional, but I have a feeling there will be many and many big ones given the families. However, we're not in the position to spend much if we give a gift. Any suggestions?
