There is no glitch. I will tell you something I have noticed though. The search function on ebay is all screwy.
It is not working properly. for example: If you enter a word with out a apostrophe in it then it wont show up properly. It did not use to be this way.
I am also a power seller and top rated with almost 10,000 feedback. Sales have slowed tremendously. I also have just over 500 items in my store
If i wasnt listing at least 5 items a day I also would be in very low sales.
Keep in mind times have changed. What I could sell a year ago I can no longer sell. Its just out of style for the new generation
My sales would range around 2200-2500 a month and now they have slowly decreased to around 1200-1500. I also do this for a living but have been doing it so long that I know I must find something different to list to pick sales up
The competition is much more challenging now. It is what it is
