Ive had my account for 15 years. Back in the day, sellers would sell something for $5, and charge $25 in postage (domestic!). Literally.

They did it to get around Ebay fees. This was the normal thing to do.

Basic maths tells you that Ebay would have gone under with this happening as frequently as it did.  They introduced postage fees to stop this from happening and create a stable business plan.

If your business plan is not going well with these fees (which in total, are average in the market - I know because up until recently, I wrote business plans and did financial analysis  and contracts for retail / tourism and corporate industries), then you need to change your business plan - that isnt Ebays fault.

If youre not really into the *selling* aspect of all this, and dont really understand business plans, or tracking everything in an excel sheet seems too much work, then Ebay may not be the place for you (often the ones who say, but im just a hobby seller!). Yes, these type of sellers will struggle. Ebay isnt geared towards these sellers. Thats why they have Gumtree. Different business plans for different dynamics. Maybe theres another marketplace out there somewhere that would suit what you do better. The biggest and boldest isnt always the right one.
