Well you are misinformed, the prices were definitely raised. Within the past 6 months since I last purchased.
In March 2020 I paid $27.71 for a 6 month subscription. Just checked the bank statement. It now costs $53.08 - almost double.
I expected an answer like that from you, but I will freely express my opinion here as this is what it is meant for.
If you are so sure the prices didn't change, how about you match exactly what I paid 6 months ago? Didn't think so.
