I needed a new printer for the kids school and came across this deal that started 30/05. Seems to good to be true. A printer delivered for $87 and $25 cashback via redemption doubled to $50 if you also subscribe to Instant Ink, which just happens to be a free trial for 6 months. So basically $37 for a printer and all the printing you can consume for 6 months.

You still need to pay for the ink (50% off), though the monthly $1.99 fee is waived for first 6 months.
