I am here to offer another point of view, and to beg you - on the contrary - TO use Amazon.
Firstly, as someone has pointed out, they are a huge, huge employer. A warehouse has recently opened near where I live, and it has provided hundreds of jobs, including to my brother who suffered the closure of his previous long term employer thanks to lockdown. By encouraging people away from Amazon, you're directly contributing to more job losses in the future, most likely. The people who work for Amazon have families to feed, just as much as those running these small businesses that you speak of.
Secondly, this is on a personal level .. remember that small businesses also sell on Amazon.
My partner and I have a business of buying old toys, making them better, and selling them. Previously, we'd have sold at local markets, but these aren't happening at the moment, leaving us really stuck. To help with this, we have started to sell on Amazon, which has been a godsend for us. He fixes broken games consoles bought from boot sales for a fiver, allowing us to then sell them at ten times that price. We buy old lego sets and replace any missing pieces so we can sell them as complete. We buy old fashioned wooden toys, give them a lick of paint and put them up for sale. We also have one or two of our own products for sale at the moment, but that's kind of an experiment.
When you're buying something from Amazon, click on 'view more offers' to make it clear who you're buying from. Often (not always though), when you click 'buy it now', you're just buying from Amazon, when there are lots of sellers who sell the same things. They will all be small businesses - so buy from one of those instead!
Finally, I would urge you to please not make this lockdown any more difficult than it's going to be already. If people on here are stressed out about Christmas shopping, non essential shops are closed .. then please just let them put everything in one Amazon basket and check out. Yes, they probably COULD buy from Facebook/Insta pages, or individual websites, but with so much on our minds at the moment, it's honestly easier to be able to get everything from one place.
The Amazon hate threads are not only saddening me, but it also scares me. Amazon and eBay for us have been a chance to keep our business plodding along. Not amazing, we're not getting rich, but we're turning over enough to keep us going.
Yes, there is a very rich man at the top of this organisation, and it's galling to think about sometimes. But at the same time, when you think about the overwhelming good Amazon can do - to those they employ, and the smaller businesses who use them as a selling platform - it's clear that there is a much bigger picture. And without that greedy git, there wouldn't BE an Amazon, my brother would be unemployed, and we would have to call it a day on our business.
So please, please, please stop campaigning against Amazon when it's such a beneficial system for many - albeit with a very rich, greedy man at the head of it.
