Now i'm really gonna sound like a cheapskate
We got married a few years ago, and got away with R25K for the whole thing, excluding honeymoon.
It was for 125 People.
Had a friend who does flower arranging do it, cost R2500
Venue plus food was R10K (we paid cash so got a small discount)
Video and Photo was R2500 and he did a pretty fantastic job.
Dress was made from scratch by someone who does it for a living, that was R3000
We put a small tab on the bar of R2000 (that was only for wine, soft drinks - hard stuff you had to pay for)
Limo Hire, plus extras such as mens suit hire and DJ was the remaining R5000
Then the honeymoon was a week in Cape Town that cost us R10000 for 4 and 5 Star accommodation, as well as flights and car hire.
At the time we just couldn't afford to have a big splashy wedding, but man I remember everything about it, the wife loved it and every person said they had an awesome time.
You don't need to go insane spending money on it, rather put that money to good use like deposit for a house.
R100K on a wedding is IMHO a waste.
