Could have said I won't zap because I'm poor and can't afford it. Is that the case, I don't know...  

 I heard someone else refer to Communism as "economics of envy" also... Is that a fameous quote, or just sort of a common saying? 

 I don't know. I thought I'd just made it up. 😅  

 Margaret Thatcher, I believe 

 I am not a communist but that doesn't sound right. Why envy? 

 You begrudge people their wealth and see it as a reason to treat them worse. 

 I am still confused. I can't relate communism with envy. Communists tend to be very authoritarian. Envy for me, goes hand in hand with capitalism and competition mentality.  

 You are confusing envy with greed, I think. 

 No communists have greed for power for example.

Fixed prices for buyers are a very doctrinaire Classical Liberal thing. 

Marxist-Leninists Communists were for fixed prices, nearly as much as Classical Liberals.

If you feel, as I do, that discriminatory pricing is an abuse of market power (even if for non-market ends), then we are in the minority, and many of our fellow-travellers really are Communists. 

 Communists didn't allow for price-discovery, tho. They centralized price-setting.

Obviously, I am a classical liberal. 

 Quite.

Nonetheless, they are among our allies on this specific issue (pricing equality for buyers), while "capitalist" FAANG corporations, our nemeses.

Hilarious really 

 I'm used to that, though. Most people I know lean left and I agree with them regularly, on economic issues.

You must associate with a better grade of Leftist :-D 

 I am probably just more open to their style of argument and actively extending grace.
