Absolutely! Ive been here over 20 years and Ive survived a few very hard lows. Ive survived through the financial crash of 2008 by adjusting what I sell and who I sell to. Im literally a hobby seller and when money gets tight, hobbies are put on a back burner. However, this is also my main source of income so Ive adjusted again. I do still have some nice items as some people do have funds but Ive tweaked to more budget friendly items and stacked them, this isnt my only ID either or platform. I retain items for events like this as they come and go. 

Costs have definitely gone up (selling) and ebay is always tinkering (although I think many tinkers lately are pointless but thats my opinion) but I would put the majority blame on the economy right now.
