I get annoyed by companies that ask me to subscribe to their spam as the only way to get deals (I'm thankful that BibleWorks doesn't have sales because they already offer about the lowest price they can). That said, some people are of the mind that a penny saved is a penny earned.
In that vein, then, it appears that WORDsearch is doing the "follow our Twitter and get a deal" game as well. I notice today that their daily deal is the New Bible Commentary (which works in BibleWorks) for $9.95.
If you're interested in hearing more sales like this, you can check out their Twitter page.
