The subscription service formerly only let you pay for two repairs per year.

Apple will no longer limit how frequently AppleCare+ owners can pay Apple for supported product repairs. As spotted by MacRumors yesterday, the company updated the AppleCare+ subscription support service to offer "unlimited" repairs across its current product line. That's much more flexible than the two repairs per year previously offered, as per the Wayback Machine.
According to the fine print, this only covers "physical damage from handling due to unexpected and unintentional events." And there are associated service fees. Fixing broken glass on an iPhone, for example, will cost you $29 in addition to your monthly subscription fee. And you can pay $299 for accidental Mac damage on top of the unit's subscription cost.
