I do a lot of Wordpress development for clients. I've spent more on themes (between $30 - $80 per theme, usually closer to $40) than I have on plugins, and the themes often include functionality I'm looking for that I might otherwise use free plugins to create in a theme I'd build myself.<p>So far the main plugin I've spent money on is Advanced Custom Fields, purchasing the repeater field and options page add-ons. Cost around $40 USD I believe. Gives me a license to use those add-ons on as many client sites as I want.<p>I've also had clients purchase WooCommerce extensions like the PayPal Pro gateway ($79) and Stripe extension ($79).<p>Also, as I continue to build out <a href="http://BostonStartupsGuide.com" rel="nofollow">http://BostonStartupsGuide.com</a>, I expect I'll purchase SearchWP ($25) and Events Calendar Pro ($65).
Have a developer's license for Gravity Forms and BackupBuddy and install those on pretty much every site.<p>If it's some small bit of functionality I will try to write it myself or do some creative copy/pasting. Most plugins are bloated with a lot of extra unnecessary stuff.
None. If I don't find one I like that I can use for free I write my own.<p><shameless-self-promotion><p><a href="http://wordpress.org/plugins/kennethrapp" rel="nofollow">http://wordpress.org/plugins/kennethrapp</a><p></shameless-self-promotion>
Typically nothing, one client wanted Gravity Forms so I purchased that for his site recently. Maybe a few WooCommerce plugin extensions, but that's about it.
