I don’t think we’ve done one of those but generally people can steer you in the right direction as to an official-official store or a good dependable store for whatever.
Here are a couple previous general threads on sourcing:
CRX’s list of suppliers: List of Suppliers
G0OSE’s thread: The BLF Flashlight / Accessory / Battery / Spares Retailers Thread with Discount Codes
Some of these come and go in one way or another - some things in these threads are dated but most are still viable.
