Like the first Destiny (and many other games for that matter), the newly released sequel Destiny 2 lets you spend real money on a currency system called Silver. This takes place in Destiny 2's Eververse Trading Company store, which becomes accessible at Level 20. The character Tess Everis operates the store again, and here is a breakdown of the cost.

Everis sells Bright Engrams, which are sort of like loot boxes from Overwatch. It works out to 200 Silver for one, three for 500, and five for 800.
