Has anyone come across a reliable online store to purchase Tacori engagement rings? The style my girlfriend likes from Tacori is around $5400 and I have found several B&M stores that have identical knock-offs for $1500-1800. In any event I found places like overstock.com that have Tacori, but they are limited and never have her specific size (5). What Overstock does sell is 50%+ off of list which tells me there are deals to be had in Tacori.
