Help With Removal Orders for Long Term Storage Fees

We have 740 products (all exactly the same size) that need to be removed and they are $6.36 a piece to remove. It’s killing us but the $1000 monthly long-term overage fees are horrible. I’m going to put in a removal, but my items are all in gift boxes. Will they put all my items together in bigger boxes? I don’t want them to sticker each one and mail or they will be unsellable. We are so done with Amazon, so bummed.
Also, are the storage fees billed for the previous 30 days or the coming 30 days? I have a storage bill coming up next week for long-term overage, but if I put in a removal order today, will that cancel that bill?
