They aren't amazon.

I just RMAed a hard drive that failed under warranty, and I had to pay for shipping. But, they will pay for shipping a replacement back to me.

It's normal. A few companies will cover shipping both ways, but most won't.

Getting upset with a company that doesn't cover return shipping is a bit of an entitled viewpoint. It's not how things work for the most part.

Most companies are under no obligation to cover return shipping. Some do as a matter of customer service, and it's apparent that you've been spoiled by that. So, that might encourage you to buy more products in the future knowing that one company covers it making the return process easy, while another might not.

I consider it a perk when a company does cover it, but I never expect them to.
