From baby clothes to popcorn makers, borrowing items rather than buying them is a growing trend
The theory is simple: instead of buying a household item or a piece of clothing or some equipment you might use once or twice, you take it out and return it.
This is great! I've rented things from home improvement stores, and it's often half the price of actually buying said thing. Hopefully this can get the price down a bit.
Sometimes it's better than the alternative. If I only need a thing once and I likely won't ever need it again (e.g. a chainsaw when I cut down trees in my backyard a few years ago), I'm willing to make the trade-off. If I bought it instead, I'd still sell for half price and need to spend the time selling it. It's a wash either way, so I'll do the easier thing.
I'll buy other things that I'll use occasionally. For example, I own an angle grinder, which I've used a handful of times. If it was cheaper to rent, I would. But home improvement stores are in the business of selling tools, so they want to increase rent enough that people will lean toward buying instead of renting.
