Culture Hustle is NOT a scam
I placed an order on August 24 and it arrived today (October 10, ordered from USA)
I went through all the issues people here complained about, non responsive support, the website obviously lying about dates, the order status on the website never changing etc etc. Two weeks ago I received a response from support that they fixed their shipping issues and the product did in fact arrive today.
So in conclusion, the company has serious issues with communication and their website has unrealistic shipping times and often lists product not in stock, but they will eventually try their best to ship their product. It's possible that their USA shipping issues have been fully resolved and future orders will reach you on the timeline they say, I can't really confirm or deny this because I would need to order something and wait 2 weeks to see.
Regardless, I doubt I will be ordering from them again either way. This is way too much hassle. But I can very clearly say they are NOT scammers trying to take your money with no intent of delivering.
