Thanks for sharing your experiences with the pricing notifications. As a dropshipper myself, I agree it can be extremely frustrating. Unfortunately, my only workaround is averaging my prices slightly higher and keeping an eye on the price changes to make sure my margins are still good.
These prices are controlled by the suppliers, so there's no way to stop the fluctuating without simply switching suppliers. This is another workaround that I have found works quite well, as some suppliers do not change their prices that frequently.
Anyways, that's just my personal opinion. I do think it is an issue however, and will be passing this feedback to our product team. Hopefully they can work on a solution for it in the future! Would love to hear other's opinions on what has or hasn't worked for them too.
