The key word her is "stackable" so the seller is focusing on volume selling which is very effective with amazon's one listing per item policy. If the item is very popular then having 600 of some item could be a weeks worth of inventory. Whereas on other sites, you would have to list on site and then everything is seller-by-seller....so if people don't see your listing or your price isn't good enough then you get no sales.
but yeah, that's just how it is. Selling products on ebay/amazon is not a guaranteed source of income so those types of businesses are inherently high-risk, especially if you are focusing on a specific product line or niche products.

Again, I understand how that can prevent a profit.
But how does it hinder you to put ads (I guess both Ebay and Amazaon have those) for your product and sell it off for half the price?
I'm not addressing that she might have to fold her business. I'm only addressing the being stuck with inventory part. That makes it sound like she had to throw it away or something.
"Stuck with" is a colloquialism. It's just saying that she'd planned to make X profit and instead will end up with a loss. There's plenty of ways to make a loss: sell it at a discount (near or below what you bought for) or spend so much effort making sales that your opportunity cost is more than your profit. The article's point isn't about how she's going to get rid of her useless inventory, so it just uses the shorthand that she's not selling at Amazon and has no immediate profitable back-up plan.
