If your venue lets you bring in cake, I will say that both Sams and Costco make sue pretty tasty cake and cupcakes.
I agree that you should talk to your photographer, and see if you can streamline the package a little. We asked our photographer to trim the package from 6 hours to 5 hours and to cut the parent album from the package and saved quite a bit that way.
Are decorations terribly important to you? We ended up putting most of our flower budget into the wine budget instead, and we’re doing old family photos as centerpieces. We aren’t decorating the ceremony venue because it just isn’t that important to us.
Definitely cut out favors unless they are really important to YOU.
How much have you budgeted for invites? You could get super cheap plain white invites from vistaprint, and then glue them in an attractive pocketfold (that way the paper quality of the cheap invites won’t matter so much). My letterpress dreams died when I realized I wanted to pay for someone to come and set up ceremony microphones.
Do you have your dress yet? From your picture, it looks like you are probably thin, which opens up a lot of used dress options to you (you can buy one up to two sizes too big and get in taken in, according to my alterations lady…obviously that would depend a bit on the style). Be sure to include alterations in the budget if you do this.
You can cut out some unnecessary paper items, like escort cards/menus and just to a big seating chart and one menu per table.
We are only printing up 10 rsvp cards (for the non-internet saavy guests), and asking everyone else to RSVP online (saving the cost of the card and the return postage)
We are skipping bouts and coursages.
Unless you have been mean to your attendants, cut what you have budgeted for their gifts by a bit. They will understand your money woes. Be sure to write them a heartfelt letter expressing your gratitude.
If you are renting linens for your venue, be sure to look into buying used ones as that might me cheaper.
Good luck. With a little work, it’s going to be just fine.
