When you purchase the 8-pack, it includes 8 returns for the year it was purchased. In other words, you couldn't complete 8 returns for different tax years.
You can still find the 8-pack for 2017 from our retail partners. Here's the link for Amazon: https://www.amazon.ca/TurboTax-ImpotRapide-Standard-2018-Returns/dp/B07KS477VS/ref=sr_1_3?ie=UTF8&qi...
What is the difference between the 8 return online deluxe version available for purchase through Amazon $32 and the online version i currently use through TurboTax site and pay $20+ for each return?
@Luke601 It's the same product, you just get a bundle of 8 returns at a small discount.
Please note that if you have the 8-return Deluxe package, this is good for 8 Deluxe returns. If you prepare your return together with a spouse, that counts as 2 returns. In the event that you have to upgrade or buy the Premium pack, you will have to pay the difference in price.
