How should I tell guest we don’t want gifts if they want to donate money towards honeymoon fund it be nice....

I don’t want it to sound rude it’s just we already live together and have everything we need but if guest feel the need to get us stuff then how would I tell them we don’t need gifts just donation money if they wanted but it’s not a necessity we can of course afford the vacations our selfs we just don’t need blenders and stuff you and Ik family sometimes feel the need to always get stuff when U don’t need it.... idk I just don’t want it to sound rude
