Most wine making stores sell 750ml (new~$1, used~$0.50) + 冰酒的细瓶(new only, ~$1 simple style, ~$3.xx for Ice Wine style bottles) Not that easy to find 1L bottle.
Don't buy from anyone u don't know, not outside of "Beer Store". U never know if people put chemical inside. UNLESS u have proper setup at home to properly soak and wash at home YOURSELF. Soak with Chlorine(~$4/kg.), use proper bottle washer(~$15+$5 adapter). Wine supply stores sell them, ask them for details.
Home dish washer and "special washer" at wine making store are both UNRELIABLE. OK to wash your own "trusted" bottles, not to wash bottles from God know where they're from. U can test my words by putting some cigarette buds in few.
