Creating an eBay auction for FBA Inventory I want to liquidate?

I have about 500 units stuck in Amazon FBA, and I’m trying to figure out how to recoup my costs.

Liquidation is an easy option, but you only get about 5%-10% of sale price back, before Amazon removal fees. Sometimes that takes it down to 1% of sale price you get back.

So I’m thinking of just auctioning off those 500 units as a bulk / liquidation offer on eBay.

For FBA Inventory Removal Orders I hear it sometimes takes 60-90 days for you to get all your inventory. Plus they are coming from 5-10 FBA warehouses, so they will come in various shipments. (Though some are saying their removal orders arrive within a week or two.)

So if I created an auction for those 500 units as a bulk liquidation auction on eBay, and it would potentially take 3 months for all the inventory to arrive, could that cause an issue, even if I make it very clear in the listing description?
