There are no words. That is just flat out tacky. You may say "no gifts" or you may say "in lieu of gifts, please consider a donation to the ASPCA," but you cannot say "give money." Two twice-married adults don't need gifts or cash prizes; that's just being greedy.
Traditionally, for a first anniversary, paper is the proper gift. Depending upon the location of the party, you could do something interesting, like a wishing well to collect cash.
Thank you for the first part of your answer the last part is irrelevant. add a comment
