What am I supposed to sell on flea now? [Discussion]

Hi all I’m having a tough time figuring out what items I should sell on the flea this wipe.

Back when FIR was a requirement for flea I used to stock up on tons a different items and make bank.

Now that hideout upgrades are FIR I’ve been literally hoarding everything up to 3 Junk boxes worth’s because I don’t want to be short for a upgrade in the future.

I know flea flipping is a thing but are there items I can stock up on and sell in bulk for consistent cash flow?
