Yes thats a good deal if your a big spender.. I wouldn't get anywhere close to that with our monthly outlay.
In fact I will only get $2000 in 3 months if I get another business trip in that time.

Look into manufactured spending techniques. You can use an Amex Serve to MS $1000 a month, fee free.
You can also buy gift cards to stores that you already shop at.
You can also buy prepaid Visa or Mastercard gift cards, usually $500 for $5 fee (and the fee is always worth it if that's the only way you can meet a signup bonus).
I'm also in a similar same position as you - I just barely spend $1000 in 3 months, so meeting anything higher than that is not possible with normal spending. But I have MS'd $2500 in one month to meet signup bonuses. I actually made money doing this because I bought Visa gift cards at a Best Buy, and Amex had an offer of $25 back on $250+ at Best Buy, which cancelled out the Visa gift card fees and still had money left over.
