The idea of it was so that one person could buy the bracelet for their partner, in the event that both parties were unable to purchase a bracelet, not the money trade which has arisen in its place. However, it was a bold move from SE, and a good one at that. It makes sense to do given that they've added an unfortunate 'downgrade' system as part of Eternal Bond which reduces your celebration and rewards to the lowest paying party (which in some cases means identical to the free one). And sadly, no refunds are offered if this occurs either.
