Empire Poker Reload Bonus Inquiry.

[Prodigy]

Recently when I logged in, I saw a reload bonus for 15% up to $100. The bonuscode was GET15, which expires August 25th. Again, when I opened Empire Poker, there is a reload bonus for 100% up to $100 from August 22nd-24th, bonuscode PLAYAUG.
My question is would I be able to make two qualifying deposits, let's say $1000 and use the bonus code GET15 and then another $1000 deposit for PLAYAUG and have both deposit bonuses going? I believe it's called "stacking".
I have seen that term before. Am i using the term "stacking" correctly? What does it mean, if I am using it out of context.

Sorry for the recent bonus inquiries and taking up precious space in the Internet Gambling forum. I am pretty new to participating in bonuses as I just concentrate on rakeback.
