All of the telescopes from Amazon are overpriced. Instead buy from a reputable retailers like Agena, Highpoint Scientific, B&H, etc…
The best telescope related deal I have seen is this set of eyepieces
Best bang for the buck new scope under $300. If you buy used, you can probably get a full sized 6” or 8” dob for $300.
After a quick look, I don’t see any scopes worth buying from the “Prime Day” list.
The Svbony 102ED might be a good deal on a refractor. But I am not familiar with refractors, and it probably isn’t the best starter scope because it requires the purchase of a separate mount, tripod, and diagonal.
