Double dipping on slot play

I've pretty much given up on the monthly casino reloads. I can't fund my William hill account and Interpoker increased the WR on BJ to 50X.

However, I did play a little slots on Interpoker in Sept and double dipped the bonus while doing it. First I waited until they have an additional promo on slots (besides the monthly reload). It's usually something like "play xyz slots and wager $400 to earn a $20 bonus or earn $20 for slot play on Thursday", etc. This is when I make my matching monthly deposit bonus (for maybe $25 = 18x WR) and while playing through the 18X WR($450) I am also going to receive an additional $20 at $400WR, thus making this about a 10x WR. I could deposit $22.22, but I just round it up to $25.

Slots aren't a good gamble but I'm not risking much ($25). I get a little break from poker and hopefully lowering the WR, I can turn it into a small profit.
