@Fuggle, I'm not a big plant buyer, but last fall I bought two of Cal Carn's mystery no-name sarrs. They came to me bare roots and already with their winter haircut. I planted them and stuck them in the "cold room" for dormancy. This past spring they busted loose and grew to be over 1-1/2' tall (maybe taller?). They were like $5 each. I would think that right now sellers are wanting to reduce inventory so that they don't have to carry them over the winter (and maybe turn some extra plants into Christmas money, too!
)...so they reduce the price and make it attractive so that people will buy them and take the risk of overwintering the plants. But, the risk is really minimal if you have a basic understanding of the care that the plants need during this time. Living in a limited space area I would imagine you have limited space for your plants so don't overload yourself just because something is a deal. Also, remember that flytraps, sarrs, some drosera, and other plants do need a dormancy period...how will you provide that?....bagged and inside a refrigerator? Lots of angles to consider. But...deals can be had...just be sure the deal is something you want.
