    I started looking myself. It was $16/bottle at Hammond Indiana a few weeks ago for -100.

    I bought 15 gal of -60 from west marine last week when they sent a 25% off coupon for all west marine branded products. Ended up paying $9.50 per gallon.

    I bought 4 gallons of -50 at Lowes yesterday on sale for 3.99. We keep it in an underground mine so really don't need to winterize but I do anyway in case we get a flash freeze late March after we bring it home

    That cheap stuff contains alcohol. I heard it is bad for rubber components and hoses.  I Think it would be ok for fresh water system but a little bit leery to use in air conditioner. What do you guys think?

    FWIW, I've been using "cheap" stuff in everything but my motors for as long as the stuff has existed.
    I have been thinking the past couple years now about not putting anything in my fresh water lines.  I blow out everything with an air compressor.  I just always feared that some residual would freeze.  But I do tend to make sure everything is out.  I don't blow out the AC first (cause I take advantage of it being primed) but I could blow that out as well.  Not putting it in the fresh water isn't due to the cost, but really just a pain to get it out in the spring (I don't put it my tank).

    I made a little hose to connect to the fresh water pump to get the pink stuff in without adding af to the tank. It has fittings for both my fresh water pump and my washdown pump. I dunk the unused end in the jug of af. 

    In the spring I just fill the fresh water tank (plus some bleach) and let it run.

    Agree, I put the cheap marine/rv -50 in everything except generator, main engines, and freshwater system. Have been doing that on my boats for 15 years. 

    Also agree with the blowout on freshwater. I attach my 6 gallon compressor to the city water inlet and blow out everything on that system at around 40-50psi.  This is my 3rd year doing that.

    One year we used a cheaper -50 and come the spring we had a number of complaints re corrosion of sink and shower drains due to salt in the antifreeze.

    I had that corrosion in my boat when I bought it but I never equated it to the antifreeze. I had to replace the sink drain. Interesting!

    I should have purchased the stuff at the marina a few weeks ago. Looking online, it's $23/gallon for -100. I use that on my engine. If there is any residual water, it only dilutes it by 20* or so. The good pink stuff is $11/gallon online right now. I have a feeler out from a place in Pittsburgh that usually sells it at a great price. My sister will be road tripping here in a month, so I might have her pick me up some.

    Just paid $7.98/gallon at my marina for the -50. Another boater asked about the -100. Said the -50 will get slushy at -20C. Im thinking of returning it for the -100 now. trying to get off of the automotive stuff I've been using.

    -50 is the burst point.  It doesn't matter when it gets slushy or even freezes...it does not expand like water so that's why it's rated to -50.  I myself use -100 in my engine and -50 in my water system.  People freak out when they put AF in the freezer and see it frozen the next day.

    I was looking through my old orders from Wholesale Marine for -100. In 2019 it was $11.56/gallon, 2020 it was $11.99/gallon, 2021 it was $13.99/gallon. This year it was $21.49/gallon. It really went up. I was going to order the StarBrite -50 from Defender. They had it for $9.99/gallon, which for alcohol free, I didn't think it was too bad. They wanted $72 in shipping. WTF??? I got the same stuff, same price from West Marine for $9.99 shipping.
