Competitive External Price Issue

Hello,

I work for a manufacturer in the pet industry. We sell 3P on Amazon, and 1P with Chewy. Every time I do a price discount on Amazon, Chewy will match it. So for instance, I had 10% off our retail price from 10/22-10/27 on Amazon, and once Chewy saw that discount, they also put the products 10% off on their platform.

Now today, much of my catalog is suppressed because the “external” price is showing as 10% cheaper than my price on Amazon. But it’s not correct. Chewy has flipped back to the regular retail price (the exact same as Amazon).

I’m not sure how to handle this in the future. The sales bump from the price discount hardly feels worth it when my ASINs immediately get suppressed once the sale ends. I can submit cases to have the external price re-checked, but it takes up to 3 days. It’s just not worth it to do a sale and then get crushed with suppressions at this point..
