Ben Sherwin and Sam Moseley have asked local companies to donate their goods and services for their big day in Cardiff next month.
The pair were forced to plan their wedding in a mega-quick 123 days so Ben's sister could attend as she's soon moving to Australia.
With not a lot of money or time to spare, they decided that getting their big day sponsored would be their best bet.
The super-savvy pair set up the blog 123daywedding.co.uk to help promote the generous companies who helped them out.
It's been a huge success and firms have included everything from edible "flower" specialists, Fruity Bouquets, to the cake company, Ice As Nice. They've even managed to secure a snapper.
The soon-to-be husband and wife from Bedwas, South Wales, also have stationary, groom outfits and wedding favours - all without spending a single penny!
Ben, 23, explained to the Daily Mirror: "I realised that people get sponsored for all sorts of things, So I started emailing firms and they loved it."
Samantha, 22, added: "We're turning down firms now because we already have what they are offering."
Between them, they've forked out for the rings and bride's and bridesmaid dresses, while Samantha's father contributed to the honeymoon.
They also plan to make a donation to Save the Children with some of the saved dosh.
