Both, pet shops and some so called breeders or multipliers as i call them are mainly interested in making money rather than the welfare of the animals they sell otherwise they would do their research and not pass on incorrect and downright dangerous information.

I totally agree with you in suggesting to get two cages and personally would never house two hamsters in the same habitat. The odds of success are far too high and i care far too much about hamsters to knowingly subject them to a high risk of injury and possibly death.
