So I'm trying to save up some money for a few things (new TV, pay off my credit cards....

) but I'm notoriously bad at spending money when it's available. So I was thinking of skimming money off of my BR, transferring it over to my neteller account and then just leaving it there. This way I could take a couple hundred out here and there, build it up to $1500 - $2000 and not have to worry about spending it in the meantime.
This may be a stupid question but is it ok to leave that much money just sitting in my neteller account for a month or 2? I remember someone posting something on here about it not being a good idea so I just wanted to clarify before I wind up losing a couple grand.
