This chair is listed at $249.00 on their website, however, the chat rep said they will be able to honour last month's deal for all OzBargainers. Enter the promo code at checkout and remove shipping insurance to bring the total down to $199.00.

Edit: This deal really kicked off and they've received a large number of orders from OzB. I have received the following email from them, "We're sending out all the Cascades we have, but yours may be delayed depending on what time you placed your order. Don't worry though, the next shipment of Cascades will be arriving in 3-4 weeks, so delays will be kept to a minimum." If you place an order now, expect to wait a while for it.
If you're looking for something to arrive sooner, perhaps look into the following deal for a similar chair at Winc: https://www.ozbargain.com.au/node/554561
@fortunecookie: Rang Buro as well - they hadn't heard of that before. As far as they're concerned, the only part difference is the base itself.
