If so, that will provide the answers to some of your questions. If it's from Petco, it's almost surely a Tremper. If it's from somewhere else, I suggest you call and ask and see if they know. As far as coloration goes, you can't tell with any reliability at that age how they will turn out when they are grown, it can change a great deal, though if you know their parentage it can give you a much more reliable guess. So I'd say she's definately an albino, Tremper if it's from petco, and wait and see on the color as she grows, if she survives. If I were you, I'd be more concerned about the tail and abdominal wrinkles in that animal (I have never seen those tail wrinkles unless an animal is sick, indicates recent weight loss, though it appears to be just starting in that one) and possible disease. I know you are working on getting the skin off. Be sure to provide plenty of fresh water, it may be dehydrated from the looks of it. Also make sure to have a bowl of calcium and vitamins, petstores often do not provide needed calcium to their baby geckos, and they often have the beginnings of MBD if they've been there awhile. Be aware that Petco is notorious for mistreating the animals in their care and selling diseased animals, including animals infected with coccidia and crypto. When the old animals die or are sold they don't even sterlize everything, so then the new animals get exposed even if they were previously healthy. From the looks of that gecko, no, it wouldn't be a good deal at any price. Hopefully it's just dehydrated from poor care or at least has something curable. I would get a fecal immediately (if it is sick, you should be able to get your vet care paid for by Petco if it is diagnosed with 15 days of purchase) and make sure you quarantine it in A SEPERATE ROOM, and don't handle your other animals after handling that one.
While it is possible to bring a sick animal into your home and not risk your other animals health, it requires very strict quarantine procedures and super-meticulous care (always feed the sick/new animals last), don't bathe sick animal in same sink as other geckos, quarantine is seperate room, and of course all the basics like don't play musical food, etc...Remember that just washing your hands after handling her may not kill or remove all infectious agents.
Of course there are people who have gotten animals that are not sick from Petco. But it is a big risk. Many people won't buy there for ethical reasons, because it supports and encourages this mistreatment of animals. If considering buying there anyway, I would automatically add a possible $100 and possible death of the animal when evaluating the price of any animal, or whatever it costs in your area for a vet visit and fecal and meds (around $100 here, it it's just worms). Of course some things are not curable, or will require multiple vet visits. If there are ANY signs of ill health, don't buy it. Remember that illness can lie hidden for months, and that a clean fecal (float to test for worms and smear to look for coccidia) does not mean that animal does not have crypto or a bacterial infection. I have also seen one person post on this forum that they got a clean fecal, but then did it again later and it turned up hookworms and something else...maybe coccidia.
I hope your new gecko is healthy and everything works out for you. It's just that I've seen so many horror stories of huge expenses, heartbreak, etc... from diseased chain petstore animals. I tell you the above as I know you have other geckos and it is important that you protect them from a known danger. Also, if it's from Petco you can ask who their contracted vet is and take it there for the fecal, that way if the fecal turns up anything you can may be able to get them to cover even the initial visit as well as subsequent care.
As for deals, I think it's a much better deal to pay $60 for a normal, healthy well-cared for juvvy from a responsible breeder or reputable herp-specializing independent petstore than $20 for a possibly diseased and likely not very well taken care of morph from a chainstore. Of course some people like to gamble, in that case just be sure to manage your post-purchase risk as best you can, especially the risk of getting your entire collection wiped out.
Good luck with your new gecko. Use quarantine. Be careful.
