Like you said, 100% het is only het when actually proven, there are shady characters out there. Including those that sell to shops.
100% het Albino comes fromm one of two pairings...
Albino x normal (or pos het that did not prove) = all 100% het Albino babies.
Albino x het albino (or pos het that does prove) = some Albino and some 100% het Albino babies.
As to worth the purchase, a het Albino is only worth more then a normal if you are planning on breeding it. And even then, not a significant increase, check the classifieds for typical pricing.
