It’s the time of year for mac software promotions. MacSanta just kicked off yesterday. This site offers daily 20 percent discounts on selected applications each day until Dec. 24. And over in Europe, mac developers have put together the “Give good food to your Mac” promotion, offering discounts up to 70 percent on a sliding scale (the more apps you buy, the better the discount). There are some really good applications on this one … and only six days left before it ends. And one more … I just discovered that MacUpdate also has a promo for the next eight days … 10 apps bundled together for $50.
