MacHeist is a website that periodically offers discounted “bundles” of software for Macs.  They offer 14 pieces of software for only $49, and two of the programs – DEVONthink Personal and TextExpander – are ones that I use and recommend.  Unfortunately, I already own DEVONthink, and don’t have enough use for the other software to justify the price.  But, if you don’t already own DEVONthink or TextExpander, it’s a great price for some great apps.
