Are these items that couldn't be legitimately rented from somewhere else? I'm personally very opposed to the practice, but am curious why people feel OK doing it.
Why do you feel OK taking advantage of a buy-one-get-one-free deal? These stores aren't stupid. They know people do this. They do a cost-benefit analysis on their return policies and decide that they're OK with this gaming because it is compensated in other areas. Their salespeople can tell prospective customers, "Hey, you're not committing to anything. If you don't 100% want to keep it, you can just bring it back with our awesome return policy." They do this knowing that most people won't even if they're not completely happy. The flip side is that we actually get to take them up on the offer.
On the other hand, I don't personally do this because I'd rather just work a little more and properly rent or buy. Seems like less work in the long run.
I'm a student so the return policy way is really the cheapest out there. As to why people feel OK doing it, why shouldn't we? Costco, in particular, offers an unusually long return policy. I don't exactly return underwear or dirty plates, but electronic devices I don't see a problem with. A good example would be needing a good laptop for about a week or two when the university Debian based towers just don't cut it anymore.
I mean, anyone who's used an IDE written in Java will agree.
It usually feels to me that if you don't want someone to take up the offer you need to have tighter returns policies. I see why companies do it, for the vast majority of people buying the product it's like an added bonus if something goes astray. This opens the system to gaming by the small minority of customers but still the benefits to the companies sales far outweigh the cost. If everyone was doing it I'm sure the companies would be a lot less generous with their returns.
Reminds me of a story a friend who works at EB Games (some campany as gamestop in america). Every week or 2 a lady would come in and exchange a game she purchased for her kids for another one, usually just falling inside the exchange period. Essentially she was using EB as a free game rental store. Eventually they cut her off but not before she had well and truly gotten value for money on whatever she had originally paid.
If there is an opportunity to have something you temporarily need and likely wont need beyond the given project, then how is that not simply utilizing the system in place? It's a life hack.
You know what? Just because it's legal doesn't make it right.
If too many people do this, then the policy will change, and ruin it for everyone else.
You pay an annual membership so that costco can locate their businesses in cheap areas zoned for wholesale/warehouse outfits, not regular retail, saving them a ton of money. They have to charge you a membership fee - it's members only shopping.
