Can anyone tell me whether it would be worth it to still use white flash considering I do not get the sales tax discount? I actually live about 30 min. away from their headquarters location in Houston, Texas. It comes out to about $500 in tax which while not entirely significant, is a good chunk of money for a college student. The diamond I''m looking at will run about 5800 with the bank wire discount + tax. My other option is blue nile. I like the hearts and arrows diamond offered by White Flash but the Sales tax is hard to get over.
