Netflix used to have their cheapest non-ad plan.. called basic plan for $11.99 (it used to be 9.99).
Anyways,.. they forced users to change to the 3 existing plans
I know there's the $6.99 plan with ads
There is also the standard plan for $15.49 with NO ads.
If I had known I needed to change plans.. I would have purchased a gift card for $16
Given no prior warning.. they would not accept the gift card I had already purchased for $15 stating I needed to change my current basic plan to something else.
Anyways.. this month I will try the plan with $6.99 with ads.. since all I have is $15 in gift card credit. I didn't feel like spending more to get about $15.49 to fulfill the one month non add standard plan.
