About workers package

Recently I got a workers package for 1500 gems, the offer popped up when I spent most of my gems and did a few battles. Will I get this offer if I have sufficient amount of gems or is it same as starters package where is it a must to buy gems to get the offer.

Thanks.

All package offers only popup, when you have less gems than needed, except the uber chest offer.
You don’t need to buy gems to get them, if you have “hidden” gems: vouchers (you can buy gems
with them), uncompleted gem dungeons, Tapjoy/Fyber, chests (only slight chance of getting gems).
Start saving your vouchers and gem dungeons (but dig to them!), if you haven’t done it already …
