Booko now calculates the savings you’ll make between the price of the cheapest store, and the most expensive store, including the percentage saved. Plus, I’ve setup affiliate links for Better World Books – not that that’s a feature as such, but it should hopefully help me pay for hosting Booko.

I’ve also discovered a couple of bugs with Booko which need fixin’, one online shop changed their site meaning I need to fix the price scraper, plus I upgraded my Ruby install without fully testing it. The ActiveRecord component of Ruby on Rails introduced database connection pooling – which is great but the default values were too small for Booko. Some of you may have discovered only half the prices being downloaded for books – sorry about that. 

Thanks to Andrew from Online Bargain Megastore, I’ll hopefully be adding http://oo.com.au/ to Booko sometime soon, bringing the total number of stores checked to 19.
