I have been buying from eBay for over 20 years. While living in the US it was very good, Also, it used to be genuine individuals who were listing on the eBay at that time. Then the businessment got on to the platform. Noe all the vendors of JUNK from especially China is on it through agents resident in the US. It is a zoo out there. One could always check and avoid 90% of them if careful.
Since I moved to Canada it has gotten worse. It is the shipping racket now. Big companies have got the 'contract' to do the shipping and customs clearance. They are trying to cut corners to sharpen profits. It takes weeks if not months for you to get your purcase what you have won. Fees are on the rise too. For some items which are not subject to taxes and duties, it is not worth it. The vendors have jacked-up the prices to cover their e-bay costs.
All-in-all, I seldom buy on eBay now. It was a good thing which is going where the dinasaurus have gone. I hate it.
