a few people have referred me to, euroboutique...

They have the D2S 6000k bulbs, for $75 more than theretrofitsource.com --- which is another source that a lotta people have referred me to.

What is so much better about euroboutiques that warrant $75 more?

Its not an issue of the cost, as I know that the general rule, is you get what you pay for... but what about the ones at euroboutique warrants $75 more?
