Can I permanently store items somewhere?

In good old CRPG tradition I'm taking anything that isn't nailed down with me. I've got half a forest worth of assorted plants and more iron ore and other crafting materials than any normal human could carry.

Now, at some point I'm reaching the weight limit of my inventory, but I really don't want to throw any crafting and alchemy ingredients away. Is there a place where I can permanently store items so I don't have to carry them around?

In the first game you could do that generally in inns, but I'm now at the first Inn in the game and see no option to store my items.

Solution 1:

In the Witcher 2 the storage system do not belongs to Inn keepers but some other people. Like for your case in Flotsam, the storage is set to a man down-stair sitting inside a bar or walking around it. (just left turn when you enter the room with fighting area) And in Act 2, is the dwarf walking around or sitting in front of the whore camp's fire.

Solution 2:

As for the permanent storage, I understand there is none: http://www.gamefaqs.com/boards/975399-the-witcher-2-assassins-of-kings/59155994
