The pic of the adult that you took from Don Soderberg of South Mountain Reptile (you really should give credit, and you probably hotlinked which you shouldn't do) is an exceptionally good example of the morph. Not all will develop such a red color; some turn sort of orange. Not all will have their pattern fade out so completely; some will still have a visible pattern.
However, even the exceptional examples start out looking similar to the baby you pictured. If you buy from a good breeder, they can probably show you pics of the parents, which will give you a better idea how your baby will turn out. Some of the biggest breeders may not keep track on an individual basis which baby came from which parents, because they just have too much to keep track of.
I will say that buying this late in the season, there is a reason the snake hasn't sold yet. You are probably finding leftovers, which mean the best looking individuals have long since sold. Another possibility is that the snake was a slow-starter, and the breeder held it back until it got more established. Or you have some possibility of finding something that a breeder thought about keeping for their own projects but since changed their mind, in which case you might find a really terrific hatchling. I would not consider any of these reasons to pass on the snake, but it is something to be aware of.
Also, I see you have gotten 2 recommendations to consider a fire (amel bloodred) instead of a regular bloodred. I like both morphs, but if it is the deep bloodred color that attracts you, then the fire will not have that. They will be a brighter, but still beautiful red.
