Just a quick little report so far. I've still not received my Space Case Titanium 4-piece, which shipped from GratefulBuys on the 11th but must be held up, lost in the mail somehow. Calling GB to inquire had me speaking to Jay who was very helpful and confirmed that delivery confirmation wasn't showing up, nor any other info on where my grinder might be! He's sending out another one and if they both somehow show up due to delays or whatnot, he'll send me a shipping label to return the extra.
Just posting to say that it was great customer service, good prices, a good reputation on this forum and other for having authentic products (There are a lot of knockoff Space Cases around, some even try to charge you the same as a real deal!) and you actually get to speak to a real person on the phone if there are any issues. Anyone looking for a grinder or vape, Grateful Buys seems like an excellent choice - they ship from California, and even have a discount code for FC which I found on the forum here. Looking forward to the arrival of the product in the next few days.
