Has anyone used this service? https://investorcrate.com It's a mystery box subscription service for bullion. You select your price amount and your metal. You receive a box each month matching your preferences. The items you receive seem to be very close to what one would expect to pay, except that you also pay shipping. So, you end up paying more than if you hand selected your own bullion from your regular online or local dealer. However, you pay for the convenience and the mystery and excitement.
