I'm an extreme couponer so pretty much everything I prep falls into the budget category. Last week alone I got $1000 worth of stuff for $100, most items varying from 60% off down to a negative price point where they paid me to take it out of the store.
I like the idea behind this post, basically cultivating an attitude of resourcefulness when it comes to prepping,looking at a single item and brainstorming 15 alternative uses.
Here's a youtuber I like named Larry Hall. Larry uses Walmart reusable shopping bags as planters for his self-watering garden. Love this idea because it makes your plants portable and cuts down on weeds. If you check out his channel, he's got some nice canning videos too.
