As the title says, I've got 3 Riot Squad Singed codes.
All of them are one time codes (can be used on one server only) for EUNE server, however, two of them should be multi codes, which also work on NA server (can test that out if You're from NA and are looking for one. If it doesn't work, I'll obviously refund You).
I'm currently accepting only PayPal with a special subject and note regarding virtual goods.
Can use TeamViewer to enter the code for You after the payment, or You can also change Your password and share the login information, which is also safe, since Riot has implemented the verified e-mail option.
Respond to this thread, drop me a PM or contact me via skype, so we can discuss the price and make a deal!
