I’d honestly pay a bit more to buy from better vendors. Price, options, shipping aren’t the things why I end up using Amazon mostly (despite not liking it).
It’s the fact that if I need to return something I just click 2 buttons and no questions asked a guy shows up at my door tomorrow to pick it up and my refund is back in my account by the evening.
If other vendors started doing that without all the caveats and conditions and such, I’d never look back.
I’m sure there is more to it but telling you she had kids so you can take care of her sounds pretty bad - even though I know it’s not uncommon.
I have had to have this talk with my parents as well since I moved to a different country at 19. I’ve told them to prepare for me not to be able to be around all the time, and luckily they have done that. It still feels selfish after so many years and they have been great about it, so I can understand this conversation being extremely difficult when the parents expect to be taken care of.
