I usually go to the local florist near my workplace to get flowers weekly / fortnightly at $30-80 for a bouqet of flowers.
This works out to be $1k - 3k per year to keep a varied bouqet of fresh flowers for decoration.
The flowers usually last a week to a fortnight when using flower food.
I live too far from the flemmington flower market to go there to buy them but know you can go there and buy from the florists/wholesellers at a huge discount (50-90% cheaper compared to buying directly from florist).
Any recommends on any sites or how to source fresh flowers for cheaper delivered?
Contact a courier that picks up flowers from the growers at Flemington markets. If you're doing weekly orders, they might add you to your the delivery list.
I'd start with contacting one of the growers that you've purchased from and ask them. This also depends on your location.
