Groupon cash amounts are marked on selected deals and Groupon cash will be uploaded into users' accounts by 28 April. For every easter egg deal you purchase, the Groupon cash will accumulate.
Groupon cash is eligible to be used on any deal on groupon.com.au until May 31, 2014. Good to combine (or purchase deals) with Groupon credit from the previous Hoyts ticket deals if you have received it https://www.ozbargain.com.au/node/139432 although you will need to note your expiry dates for that credit.
I'll list a few examples, but plenty more there, not a bad deal if you were thinking of purchasing anyway.
Travel Deals - found by clicking the travel tab http://travel.groupon.com.au/ The bonus Groupon Cash appears on the top of the first photo related to the deal.
NOTE that some travel deals allow multiple vouchers to be combined to extend your stay - may be worth buying multiples of the fewer nights option and getting multiple Groupon cash credits.
