Gems are available in the store. In the UK they are:
£2.99 for 50;
£6.99 for 110 (with 10% bonus);
£13.99 for 240 (with 20% bonus); etc
But, if 50 are £2.99, then 2*50 plus 10% should be £5.98 for 110, similarly 200 as 4*50 would be £11.96, 20% extra being 240 for £11.96 not £13.99. These mistakes continue for all prices.
Now I don't mind the rounding to the nearest 0.99, but the rest of the pricing is misleading. In the UK, you are not allowed to show something as 10% extra when it's clearly not.
But Funzio have chosen to ignore my support message about this. They said they'd pass it to developers for their consideration, but the pricing is still all wrong. It's the same on Crime City.
I'm just a bit shocked that Funzio don't seem to think it matters. This is something they should be correcting immediately, it's fundamental. It's not like I'm moaning about a nerfed weapon!
