Pharmacare -- extremely fast shipping, great stealth, great hash. Usually has some benzos and roxis in stock.
Importdirect -- Friendly, great customer service, quick shipping, awesome hash.
House of Spirits -- I know others have had issues with her (him?), but my experiences have been very good. Shipping is a LITTLE slower, but only by a day or two. Great acid and MDMA.
Downtherabbithole -- Good DMT (not the BEST I've had, but good), ships within a few hours, some of the best stealth I've ever seen.
That's it for now. I'm fairly new to this, so my list is a little short right now. I've ordered from a few other vendors that were fine, but the product was either only okay, shipping took a little longer, or both of the above.
Curious to hear from others.
