I live in NYC, where there's BSS EVERYWHERE, lol, so there's multiple places you can get it here. I actually bought it this morning at Uptown Beauty Supply which happens to be the store location of Bluebeez.com. For those who live in NYC and arent too far from manhattan, bluebeez.com prices are LOWER in store. For example, the garlic mask online is $19.99 but I purchased it this morning for $17.99. There was a mask I'd seen on the website for 22.95 and instore, it was 19.99. So I don't mind making the trip to save on shipping AND prices, lol. I've gone to the beautyofnewyork.com store only once but I've never purchased from them online. They have decent prices as well.
ETA: The one I purchased says 'garlic mask' not 'treatment'. It's the one with the alter ego logo in a little orange box and green fields behind some garlic, lol
