I've got so used to buying gems at 30% off that I was gobsmacked when I realised that the 530 gems costed 15,99 on my other farm and it only being 20% off.
(It's not the gem / coin amount on my TwixAndScones Farm)
I kinda just assumed when gems went on sale it was the same for every farm with it being 30% off. I guess not
Anyways, I now have 5 Frozen Bluebelle's on other farm. So 10 in total across 2 farms.
Very cool.
