No coupon code, but the price on PIA's sign-up page has 20% off yearly subscriptions for Black Friday.
US$31.95 for the year (it's actually cheaper than a 6mth subs!!)
Dunno if existing subscribers will be able to get at that price, but new ones will.
Presumably valid 'til 7pm Sat EDST(midnight Pacific ime in US).
Price in title thanks :-)
Thanks for the heads up OP
