Click Frenzy 2016 includes 210 online stores
210 brands are taking part, but some big names from 2015 have dropped out.
When Click Frenzy 2016 kicks off at 7pm AEDT tomorrow (May 17), it will have the largest number of participants so far.
210 brands have signed up for the 24-hour online sale, according to the organisers.
That said, a comparison of the brands who participated in the most recent Click Frenzy event last year suggests that more than one-third have not returned, so you'll still have to dig around carefully to identify the best bargains.
Click Frenzy says there will be savings of up to 90%, but hasn't yet revealed details of most deals. We'll be keeping track of all announced deals here at finder.com.au and helping identify the best bargains.
Typically, deals are staggered over 24 hours, which helps minimise the risk of a server crash. The first-ever Click Frenzy event in 2012 suffered from major technological outages, but the event has been more stable in recent years.
American Express has already announced a partnership with eight Click Frenzy retailers to offer additional cashback on items purchased during the sale. If you're after particular brands, it can also make sense to check if they're on offer through department stores as well as through the brands themselves.
