Do you think this will affect upgrade prices in any noticeable way?

 

It's only raised for accounts that had never membership on it, and then goes back to the normal prices.

 

What's the price of the membership buying and did they raise all the prices for credit card's SMS etc?

 

It's $7.95 now, and yes they raised all prices, but if you already bought member on your account once before, the prices will still be the same.

Unless you let it run out and lose the 'loyal' status from what I understood.

 

Lol to Jagex. This increasing was maybe due to Bot Nuke as it lost many players... So Jagex will raise membership to get equal again
