(I believe gift cards are only sold in the U.S. and Canada)
Step one:
Obtain about $50. (This is the recommended amount because any less and you'll be crawling back to the register seeking more money to donate.)
Step two:
In America:
Go to "CVS Pharmacy", "Walgreen's", "JewlOsco", "Wal-Mart" or many other retail stores and buy a "Visa pre-paid gift card" or a "Mastercard pre-paid gift card"
In Canada:
Go to "Shoppers Drugstore", "A&P", or "any major grocery store" and buy a "Vista pre-paid gift card" or a "Mastercard pre-paid gift card"
Step three:
Create an account on "http://www.paypal.com" and then log in.
Step four:
Click on "Add funds" at the top in the tabs.
Step five:
Fill out the information on the "Add funds" form with your gift-card. $50 should now be on your paypal account.
Step six:
Go and donate to this server.
Well,I dont think this way works for singaporean.I had been checking out 7-11 and all those shops and they dont sell this.(Very inconsiderate of them).But according to some other private servers 7-11 sell paypal cards or w/e that is.So u could just go and try ur luck.
After u donate,private message Bubbles ur ID,IGN,paypal acc ID,amount u donate and what u like.
I dont take credit for this.I got this thread from another P server.
