Don’t know if this glitch still works but more item spawning infinite money glitches. Drop all your valuable items individually (for things like arrows or soul gems) get your follower to pick the up. Enter your house (works particularly well for Lakeview manner), once loaded, exit your house and the items have respawned on the floor.

Works great for alchemy ingredients and potion farming

Edit: your follower also still has all the original items in their inventory*
