Looking for seller feedback who carry "Art of Where" Print on Demand products?

[SavagezillaShop]

Hello, I've heard that the Print on Demand company "Art of Where" has superior quality fabric and really great Print on demand items but their shipping time is extremely slow, which makes me nervous.  Was looking to see if there are sellers that can share their experience with this company. Are orders fulfilled and shipped in a timely manner? What's the typical wait time for items to be fulfilled and shipped?

Like most sellers, I sell on Facebook/IG and wanted to know if Art of Where at least fulfills their orders quickly? FB is strict about fulfillment time. 

Please if anyone would share their experience regarding fulfillment & shipping with this brand, it's the only thing keeping me from moving forward with them as my POD supplier.
