Also I am not sure what the problem is that is unique to those with ADHD. The issues raised are the same for everyone.
The joy of ADHD is that issues that seem the same as everyone else's are often far more difficult/easy to manage.
A de facto standard in the US.
Some other countries have stronger consumer laws in place that define statuary return policies.
Amazon is 30 days, and it has made 14 days look stingy this day in age.
How is it more wasteful than keeping something you're not going to use?
The wastefulness comes from the fact that the barrier to purchase is pretty low, given the ease of return, so one is more likely to buy an item which may end up in the trash in 14 days (30 for Amazon).
If I absolutely couldn’t return a product (aside from defects), I’d not buy a lot of items in the first place.
(I say this as someone who is guilty of plenty of “trials”).
I’m actually travelling through Japan right now, where one can visit a Yobadashi or Bic Camera, these stores are great, because all their tech is out and able to be played with, without explicitly getting assistance from a staff member. It’s obviously not the same as bringing a camera etc into the field to test, but it goes a long way in deciding if something works from an ergonomic perspective, before purchasing it.
Making a purchase is very different from getting one to try. Beyond a 14 days return policy, you start getting abuse from people trying to exploit the exchange policy.
As many people say, 14 days is kind of a standard. Many companies have even fewer days so read the fine print before you buy. If you don't like the return policy, don't buy it.
If you absolutely have to have one on Day 1 but don't feel 14 days is sufficient, maybe evaluate why you need it on Day 1? Wait for some other people to have it in their hands, and the rentals/loans usually start a few weeks after launch.
