Places to get gianduja in Houston?

My fiance loves hazelnut spreads like Nutella, but has been craving the more authentic (and less processed) gianduja lately. He tried to order a jar directly from Italy but for some reason they put it in a parcel bag instead of a box so it came smashed to bits and therefore inedible due to the glass. Given that Houston is one of the most diverse cities in America, surely there has to be a store that sells gianduja (also spelled gianduia) somewhere in the city limits. I've been searching online but all that comes up is stuff made with gianduja, like chocolates and crepes, but we're just looking for the plain jar of it. I'd prefer not to order it online in case the same thing happens twice, thus the search for a brick-and-morter place that sells it. If anyone knows where we could get some, we'd really appreciate it!
