Unfortunately encouraging people to buy from pet stores is really not helpful at all. It may save the one hedgehog, but it encourages the store to stock more and more hedgehogs because they sell. The fact that she kept getting pregnant sends up my red flags as well - I wouldn't encourage anyone to buy a hedgehog from a pet store that doesn't bother to separate by sex & avoid pregnancies. Not to mention whoever takes her home (or any other female from the store) runs the risk of getting a surprise litter and all of the headaches & worry that comes with that.
I understand the concern over individual animals. It's hard to leave them there & to not want to help them. But you're really not doing anything useful at all in the long run by supporting pet stores that put animals in these situations, you're only contributing to the problem.
