There are so many options other than benchers. Siddurim, tehillims, etc.
Artscroll Shas, Shulchan Aruch, new Tur, etc.
Seriously, even at $2 each and 200 benchers, $400 is a drop in the bucket for a wedding. Making a “Takana” wedding (one man band, <400 guests, small shmorg, etc.) and a girl who doesn’t need a brand name shaitel will save real money.
