I was looking at printers and came across this. I haven't done it so can't guarantee it works.
This printer is $119 at warehouse stationary.
10% off coupon would bring it down to $107.10
Cashback would bring it down to $67.10
If you sign up to HP instant ink then you can double your cashback. Costs $2. I think some cheapies have referral codes from what I've seen on previous posts, but it also looks like you can try 2 months for free. https://www.hp.com/nz-en/printers/instant-ink.html

With doubled cashback that would put it down to $27.10 or $29.10 if you paid $2 to sign up to instant ink.

So
1) buy printer (guest/new account to use code)
2) sign up to instant ink 2 month trial
3) Apply for cash back
4) Profit???
