Why won't it let me buy all the lindens i want when I have money to buy them?

[Toxiclucious]

I use to be able to buy the exact amount of lindens I want but now its saying I have a limit?

Everyone has a limit.  The longer you are a resident the higher the limit goes until it tops off.  New residents are restricted in how much money they can spend for the first few weeks.  This prevents people from signing up to SL just to launder money.

The first week you are a resident your limit is $30.00 US Dollars.  The Second week it goes to $100 then the next week to $300.  That limit holds until you are 28 days old then goes to from $1999 up.  It can be higher than that if you own a business in SL or RL.
