I was looking around for an actual ECoins package like the other companies do in their own game's currency. Instead of the amount of donation and in return, the ECoins, I would rather not have to deal with the constant currency exchange rates.
Had read a thread of someone complaining about PaySafe Card worth $10, but could not get 500 ECoins due to exchange rate. Was 0.47(?) short for a 500, which a Mount is worth. That was unfortunate for a potential customer.
Would make sense if you had packages available on site starting from $5: 250 ECoins (no bonus ECoins), $10 500 EC with 10% bonus, $20 1000 EC with 15% bonus ECoins. See image below for example. Let me what you think.
Edit: And if anyone wants to donate more than $60, the bonus remains the same regardless of the amount donated. A $100 would still come with 25% EC bonus.
