I imagine it will be like pricing for possible hets. So maybe a 100% het toffee goes for $1500 and het albino goes for $100. Then maybe a het toffino would be $500 or something like that. So you pay a little more to gamble.
But you're correct that it will be necessary to hopefully have some phenotypic differences be evident at an earlier stage. If the toffees really are identical to regular albinos as hatchlings, then you'd have to wait a while to know if you lucked out and made a toffee/toffino or albino.
