look in the yellow pages for bridal shops near u , get to try different dresses bearing in mind your budget , dont try sth thats over ur budget.
try ebay like the ladies suggested.
u can guy bits and bobs for here and there like tealights from asda etc,.,,,
write everything down , like the theme for ur wedding. all details from ribbons to flowers etc. see what the venue includes in the package , for exaple the wedding cake teirs were included in the package....
check the prices include VAT !!
try confetti.co.uk ...they have shops round the country and they also have discount outlet shops as well . so u can get loads of bargians. dont buy anything until u know exactly what ur theme will be so u wont change ur miind later.
go to wedding fayres . there are loads going on cos summer is a high season for weddings . im sure there would be one round bristol this march. get the news paper , there would loads of adverts there....'
good luck !
