Microsoft will give you $10! (For spending $70 on Xbox Live)

So, here's an interesting promotion. A press release just hit the ol' Joystiq inbox, claiming that those who buy all of the Xbox Live Summer of Arcade titles will be treated to 800

, also known as $10 in Microsoft's funny money. This calls for copy and paste!

• July 22: 'Splosion Man

  800 ($10)

• July 29: Marvel vs. Capcom 2

  1200 ($15)

• August 5: TMNT: Turtles in Time Re-shelled

  1200 ($15)

• August 12: Trials HD

  1200 ($15)

• August 19: Shadow Complex

  1200 ($15)

Just adding those up -- carry the one --- that's a free $10 for spending $70 on Xbox Live. Keep in mind it's $10 you can only spend on Xbox Live (or Zune Marketplace). While the deal might seem silly at first glance, it does essentially boil down to five XBLA games for $60, the price of one retail game. And, as another Joystiq editor pointed out, that retail game could never be 'Splosion Man.

It's a nice bonus if you already plan to pick up all the games. If you don't, you'll be saving money anyway. Everybody wins!
