Aged inventory issue

I got a notice that I have inventory in an Amazon warehouse that’s approaching 180 days and I’ll get charged $0.87 cents per unit. There’s about 400 units that are going to be hit with this charge every month. I don’t have the sales volume to move all of these units before getting charged an insane amount of money. It looks like recalling my inventory is the best move and I’ll pay the $1.07 per unit to recall it. Anyone else have any suggestions of how I should handle the inventory issue without paying several hundred dollars in fees?
