I don't know if it's the fact that magicwebstore uses commas in their url or that primal considers all urls to stop at commas is the problem but somethings got to give.

That comma is a perfectly legal character, but primal is probably saving from more broken urls than not for considering that people are going to use a url mid-sentence.
