Is at Bassendean (WA) store at least. Marked as $22 on the rack at the front / middle of the store.
I had troubles getting the $22 price this evening - needed multiple staff to assist. They tried more than once to do a price adjustment but "the computer said 'No'". In the end one of them found that the vouchers were mostly marked with $35 price 'internally', but with a $45 cover over the top. When he found one with $45 price on the actual voucher, it scanned with the $22 price.
3mths use via $20 referral ( https://www.ozbargain.com.au/node/880337#comment-15989228 ) + extra $7 payment - credit/thanks to @WatchNerd
use the ozbargain referral link pool if you need that.
So you didn't Belong then?
