This is a quick episode but I think a valuable one, Kaatz Bros has a great page on their site detailing what glands they buy and how much they pay. Of course all prices are subject to change, but this is a great resource for trappers to quickly check and get an idea of if they think it would be worth it for them to save glands for their catch. In general I'd say if you are catching big numbers of a particular species, then it is likely worthwhile saving the glands to sell or trade with a trapping supply dealer.

Also be sure to check out their DVDs on how to get the most out of your catches particularly where glands are concerned - https://www.kaatzbros.com/product/glands-a-trappers-commodity-dvd-with-kyle-kaatz/
