Capitalism 101: if the lowest price product in a market raises its price every other product is free to raise their price too. Check out the prices of washers and dryers in the US for an example. The average price increased once China tariffs were in place, including those made in the US. You're welcome to do your laundry by hand but that won't work for most of us.
You don't have to do your laundry by hand. There are millions of laundries on the street, and in housing complexes. I live in an apartment complex. I have a washer & dryer in my apartment, but I could go to the laundry of the complex if I wanted too. I could also go to any one of 3 different laundromats that are within a few blocks from me.
If people would do THAT, instead of stupidly paying the higher prices, which the seller should know he can't do, you would have no problem. You are partially creating a problem here, where there need not be one.
When the seller reduces his prices back down again (due to reduced sales/income), THEN you go out and buy your washing machine (at the MARKET PRICE)
PS - I taught microeconomics 101 in college for 3 years, and now you get the benefit.
