Will Amazon take me to collections for removal fees, if I shut down my account with inventory left in stock?

I’m very much in debt and just want to end selling on Amazon – I have spent way more on Amazon than I’ve ever made, due to shady competitors attacking me and having my inventory destroyed by Amazon in the past.

I was trying to sell off the last of my inventory, but my competitor keeps shutting me down by reporting me, and I don’t have the money to hire a lawyer anymore. At this point I just want to shut down my store and focus on other projects, and cut my losses.

If I block Amazon from being able to charge me (credit card, bank, etc), and shut down my account and walk away – would they come after me for the ~$500 in removal fees for the inventory I’d leave behind? Would I have collections come after me, or anything serious like that, that would affect me in the future?

The product I have in stock is a cheap $6 product, my profit margin was $0.50-$0.80. So removal fees would just eat all that up. I know it’s a terrible price point, it was one of the first products I sold, I just have a ton of inventory left (1000 units). On ebay it only sells about 5 units a week, it’s hard to get rid of. Amazon was the only place it really sold well.
