A dead toaster is a minor inconvenience. You can go without toast for quite a while. and a toaster can be replaced at any department store. You can carry it home and plug it in. Or order one online and have it at your door the next day. They are cheap enough and unimportant enough that there's no real downside to making price the dominant consideration.
A dead washing machine is a bigger deal, especially if your household has a few kids. You can't go without doing the laundry for very long. Replacing a large appliance involves scheduling a delivery and possibly installation, and maybe the schedule is already full until next week and you'll have to take a day off work to be home for that. I'll pay quite a bit extra to avoid that any more often than necessary. And that doesn't consider the value of the daily satisfaction of using well made appliances. They feel solid, they work without glitches, they are quiet, they are consistent, you don't worry about them.
Even with a toaster some of that applies. I've had toasters that were a daily annoyance to use. They burnt the toast, or toasted unevenly, sometimes randomly, or if you were making a lot of toast the subsequent batches would come out differently from the first. It's worth something to have a toaster that just reliably makes toast, the same way, every day.
