Where do people source half wine barrels to use as planters (for less than $100 AUD each pls)

I’ve been searching on FB marketplace and most sell for $100+ per item 🙁

EDIT: I’m looking for genuine wine barrels (previously used to age wine) as they look better (and are probably more durable) than planters that are made to look like them

Also, Are there alternatives to these that will achieve a similar look for an outdoor garden?
