Find a store that sells products with high value-density and does full cash refunds for unopened products, buy $1800 worth of stuff, then return it the next day and ask them to put the refund into a different account/cash? Alternatively, if online gambling sites are legal in your area, you could sign up to one, convert your money to chips, and cash out into a normal bank account. If it's one that gives you a little extra credit for free when you join, you could place that on low-risk bets, and probably even end up with more than $1800 in the end. Just don't get hooked. ;) ... all the ideas I'm having sound like money laundering. Oh well, I guess that's what it is, really, albeit not for nefarious purposes.
