Cheaper ways of catering please?!

The cheapest would be pot luck where each guest brings something, would be really nice at a very relaxed wedding. You could also shorten your day so you only eat once, we're doing that, morning ceremony, afternoon reception so we'll just have lunch with people. And it will be afternoon tea rather than a three course meal so much cheaper. You could get married late afternoon and just have an early evening buffet if you want to keep the evening atmosphere
