Two issues discovered in the Finding API findItemsIneBayStores:
eBay API has apparently changed without notice. Items that can take a list like categoryId require parentheses () and do not accept brackets [] like we are using.
ex.
categoryId(0)=3411&categoryId(1)=3412
URL needs to use https. We're using http.
