The 1500 runecoins shown under the Gold Package benefits, are the additional runecoins when you get Gold package, and remember it comes with Bronze and Silver benefits, where Silver Package contains 500 runecoins. So it's 1500 + 500 = 2000 runecoins. You'll get 2000 runecoins if you purchase Gold package, hope I made sense
@ Safe Death,
Your normal membership as well as the amount you're paying for your normal membership will be paused, so you won't be paying for your normal membership until the package you bought has finished its time (3, 6 or 12 months). Note: When buying the packages, the payment is in 1 hit, not per month.
