Just found about this now, and have been with Youi since May. Didn't get no voucher, tho. Will have to hassle them for it. If it materialises, it will substantially offset the $423 I paid them for it! (as am about to book a $150 pre-purchase inspection through autoguru anyway)
Update: Youi is saying I needed a promotional code from AutoGuru before acquiring the policy. IOW, that it's a targeted promotion. I didn't get that from the T&C's at all!
Thanks op
