Can I use the limited time plan on sale for $53 (1GB of data with 300 minutes) as a tab plus plan?

I want to buy a new s6 phone which is currently on sale for $0 with a tab plus plan (according to my local Koodo store). Would I be able to use the tab plus plan that is currently on sale for $53 with 1 GB of data and 300 calling minutes? If I were to use a regular priced tab plus plan, would I still have to pay the $21 on top of each bill? The website is not updated on sales so there is a little confusion.
Thanks in advance for the help.
