The annual MacSanta software sales event is back, offering changing daily discounts on different selections of applications on a daily basis up to and including Christmas Eve.

Each day, from 1 December until 24 December the MacSanta website is offering 20 per cent off the cost of products from five different developers. Deals are being made available for just 24-hours, until a new series of deals are put in place.

After each day's deals are done, the Extended Deals list is updated to offer a 10 per cent discount against the previously Featured software. These deals last until 31 December.

Participating developers include Rogue Amoeba, Bare Bones Software, App4Mac, and many more.
