On topic, however, I would trust any RuneScape gold/account selling website over Sythe. Why? Because those people are out to create a successful business whereas 100% of you dweebs on here are out to get all these tiny, successful bullshit trades like "1 pin 4 20 d stonez!!11!" and then when you get the big whammy, a lvl 120+ with 50m on it, you'll take it and run.
I trusted them! I bought 3M from them for $9.99 USD and it was delivered to me within 36 hours. I told them not to train combat and they listened. They did OAK PLANKS ftl but they satisfied me
