Sorry to hear about your misfortune to deal with your petstore... if it were me I would have some 2nd thoughts about purchasing there again.
There are some great breeders in the US.. there's no need to get them from a petstore. Warren Treacher for example has beautiful sandboa's and is a great guy to deal with.

He also has a book on sandboa's with locality info, care, morphs, etc. Well worth the money in case you're interested in reading material on the reptiles you intent to keep
