No profit in Facebook Marketplace anymore

I'm not sure if this is the right place to post this, but I need to get it off my chest.

Last year I had an abundance of items to buy on Facebook marketplace and flip for a profit on eBay.

I stopped flipping around 18 months ago but have recently wanted to get back into it.

So here I am, spending hours trying to find deals in different niches from Facebook marketplace, but there's absolutely nothing. I've been looking 4+ hours per day for over 2 weeks and I've not found anything that would give me over a 2% profit (on items £100 and under).

It's actually boggling my mind.

Is anyone else having this same issue, or am I just getting very unlucky?
