When would be a good time to receive monetary contribution?

hey you gotta get things done right? so get it done.. the second you need the money they offered (they offered didnt they?) go for it.. have your fiance tell his parents the EXACT things you need it for. this way its not like "wheres the money, i need it" it'll be more like " hey mom we have to pay for this and this and we're running out of time" goodluck
