Yes, they occasinally drop a freebie in my account too though I have never won from them. To make matters worse, there is nearly always a 100% match coupon associated with the promo and I promptly lost on them.
However, my main problem with Club World is that though it states in the message box that they had sent me an email informing me of the freebie I never received them. It's different with All Star Slots as many months ago they constantly send me $50 free chips. Same story though, never reached cashout status. Not that I am complaining though.
