There are several points to remark on here.
There are a good number of species and cultivars of Crocus with flowers that could be described as lavender-pink, but forms of Crocus with warm to neutral pink tepals are rather uncommon. Probably the best known and most available is the early-blooming Crocus tommasinianus 'Roseus'. This may likely be what Brecks sells as 'Pink Snow Crocus'. However, Breck's is infamous for selling plants using pictures of doubtful hue. Even Crocus tommasinianus 'Roseus' does not usually look quite so warmly pink in real life.
A comment was made that autumn-flowering crocuses are more likely to be pink. However this is a confusion based on the common misuse of the term "Autumn-crocus" to refer to Fall-blooming flowers of genus Colchicum. The plant pictured in Post #3 appears to be a Colchicum. Though the flowers of Colchicum may bear a passing resemblance to those of Crocus, the two genera are not closely related.
Colchicum is in the family Colchicaceae, while Crocus is in the Iris Family (Iridaceae).
Of course, there are also many other low, pink-flowering plants. For example, Tulipa bakeri 'Lilac Wonder' is indeed a Tulip (Tulipa) in the Lily Family (Liliaceae), with only the most broad and general of similarities to Crocus.
