Pure VPN is normally US$10.95/mo. They are doing a Halloween Deal at the moment with 85% off (US$1.65/mo) however before leaving the site they offer you a Halloween "Surprise" deal for 86% off (US$1.48/mo) with their "best VPN deal".
Cashrewards are offering a 50% off cash back on top of this*, with no coupon required which would drop it down to the below is clicking through from there first:
US$44.40/5 years ($64.38), or
US$8.88/year ($12.87)
US$0.74/month ($1.07)
US$0.17/wk ($0.24)
*Cashrewards cashback is eligible for new PureVPN customers only. Cashrewards 50% cashback ends 10 November 2359 AEDT, not sure when the PureVPN deal ends but possibly earlier.
I'm not 100% sure that the pricing is in USD, but if the site converts to AUD first then it's even cheaper.
Without cashback it's still 86% off, working out to:
US$88.80/5 years ($128.76), or
US$17.76/year ($25.75)
US$1.48/mo ($2.14)
US$0.34/wk ($0.49)
Is this VPN any good?
