I was about to buy a backup tool for my mails in my MAC and ended up at the tool named Mail backup X. you know what? the price last week was 79$. what i found today? its 39$. man. they are running the xmas discounts. got the tool at far lesser price. had been trying the free version for past 10 days. working great with backups. feeling lucky to have waited for 10 days. the 4 in one tool is now mine at half the price.
